IPv6 would have much higher adoption rates if it was just IPv4 but with 128-bit addresses. NAT is a much more sensible method of separating local networks from wider ones, rather than just assigning almost half of the address space to each subscriber.

>>106906949

Is IPv6 supposed to supersede NAT? That sounds like less security since it bleeds more information from the intranet into the internet.

>>106906949

>>106907015
>if it was just IPv4 but with 128-bit addresses.
It is. It's 4 times the size.
The way it works is actually way more simpler because the larger address size solves a lot problems on its own.
It's written in hex because otherwise it would be too long to write.
If you want you can write an IPv4 using IPv6 notation:
192.168.1.1 would be ::c0a8:101.
192 is c0
168 is a8
1 is 1
01 is 1
You can also do the reverse and use IPv4 notation on a IPv6.
One of 4chan's IPv6 is 2606:4700::6813:ea20 which would be 38.6.71.0.0.0.0.0.0.0.0.0.104.19.234.32 using IPv4 notation.
As you can see, hexadecimal is much more compact.
IPv4 notation on an IPv6 address is not officially supported so it is not being used anywhere.

>>106907782
>>106907805
IPv6 addresses are ephemeral by default. A device can have multiple addresses, an IPv6 usually lasts 1 to 5 hours if not statically assigned.
If an ISP is not retarded it will give you at least a /64 subnet, which means the first half will be decided by your ISP and the second half is decided by you, your router or your devices, according to your configuration.
I have a /56 which means my ISP controls the first 56 bits of the address and I control the remaining 72 bits.

>>106907782
The IPv6 device can assign any random addresses within your subnet, and in my network settings there is a privacy checkbox for this.
If you run a server, you can have your static one, if you don't, you can do any random thing within your /64.
If you want to run five webservers on different IPs on the same machine, all on port 80 and 443, you can do that as well.

I once evaded a SYN flood that was so powerful that the ISP blackholed my IP.... by simply using a different v6 IP within the subnet.
IPv6 also protects me from shodan and other scanning bullshit. While they can scan the whole v4 range easily, good look in randomly guessing the v6 i am using.

>>106907873
NAT is a done at the router and takes away a ton of compute resources.
You do not "open ports" on IPv6, they are already open, you simply don't drop the incoming packets, usually the default behaviour on the firewall configuration is to drop them.

>>106907859
>>106907897
The hexadecimal is fine. But while a device could use a random IPv6 address, in reality it just gets set to the MAC address unless specifically configured otherwise.

>>106907954
>while a device could use a random IPv6 address, in reality it just gets set to the MAC address
Literally a skill issue.
Every device supports it, because it is in RFC 4941. If your device doesn't, then blame your OS for not fully supporting IPv6.

>>106907954
Yeah that was the retarded behaviour it had before. In 2007 the IETF published RFC 4941 which fixed that privacy hole by randomising the last bits assignable by your devices.

Meanwhile in reality half the ISPs outside of korea and some parts of Europe don't even support IPv6. You literally can't GET an ipv6 address on any of the fiber companies in my state. It's IPv4 all the way.

Frontier is /allegedly/ rolling out IPv6 support the same way they have been for the last 3 years. They were initially planning on something like /120, but their engineering team bitched about it. 2ish years ago they were waiting on firmware fixes from Juniper. Who knows what the hold up is, but it's been at least 3 years at this point and no progress.

Ironically, comcast has zero problems with ipv6, although you may have to inquire about it depending on the region you're in.

>Copy 15 different addresses and pollute your clipboard reel when you could punch in 4 short numbers for each based off a pattern of what category of device it is and where it's located in the building.

By the time you find the first address you want in your massive text file, I've already pushed the new firmware blob to 5 of the 7 3d printers that need the hotfix to run the new polymer filament and am pulling logs from the CnC lathe to see if I can figure out why it crashed both of the #7 reaming tools overnight before my coffee finishes brewing.

this works with mDNS, which doesn't need any DNS server, it's multicast.

And if this doesn't work, because your device doesn't implement basic standards, you just do the thing on your router. Your router is running its own dns resolution, right? Then you have http://hostname.lan or whatever you have configured.
If your router has an outage, you don't have a connection anyway.

>We gave up the fucking world for "human readability".
And yet people like you insisted that IPv6 was the way forward despite all the pleading to the contrary by people who actually had to work with stuff in the real world. Is IPv4 perfect? Fuck no. The limited space is obviously a problem, but what the retards designing the v6 spec failed to grasp is that not everything in the real world works the way people in the tech sphere think it should. Companies will jump through insane hoops to avoid rebasing their infrastructure because doing so is risky and risks are expensive and scary.

Should you be direct connecting to IP addresses for anything, let alone everything? Fuck no, but it's going to keep happening because nobody in their right mind wants to setup all the extra crap to connect to a printer. When you start designing stuff based on abstract ideals and not what operations technology is dealing with in the trenches, you get pushback. The fact that people keep being surprised by this should tell you how dumb spec designers are.

I can't tell you how many times I've had to explain to PBX people that it doesn't fucking matter what they think the best way to use a desk phone is, people who have been using landlines since the 80s expect the phone on their desk to behave like they did back then, and they will get very angry when it doesn't. They're the ones making shot calls. You cater to them, or they make a stink about it. That's how the world works.

Meanwhile in delusional spec design land they're phasing out long term SSL certs because that's "more secure". Sure, it is in principle more secure, but I can guarantee you that sometime before 2030 we'll be reading about someone dying in the mountains because some cell equipment with an expired cert couldn't process a 911 call.

The real world is full of laziness and legacy. If your spec fails to account for how people actually use things, it's shit and people won't adopt it by choice. End of.

You actually can't assign hostnames to a lot of industrial equipment because it's locked down.

Again, it's nice in theory, but in the real world things suck. We have several large format printers that can print D/E sized paper, and I think only one of them allows you to assign a hostname. Should this be the case? Again, fuck no. But it is the case, and telling people working with this shit that it shouldn't be is about as useful as the people protesting whatever the current monthly trending topic is on college campuses.

Sure, you could abstract it away and put it on the router, but that's just one more thing that needs to be correctly updated. In a shop where you have dozens of machines with static IPs being added/removed every month, you're just adding points of failure. Believe me, I wish there was a sensible solution that applied to everything we have to deal with, but there just isn't. It was enough of a nightmare for my predecessor to even get the network organized reasonably well. Once that got setup and we stopped having outages the suits were on board with aggressive network upgrades, but getting over that first hurdle took 4 years of back and forth arguing.

Now imagine that bureaucracy in a company the size of Frontier, and you'll start to understand why IPv6 isn't making any progress. Even the people that genuinely want it have no idea how the fuck to even begin implementing it.

In that case, you shouldn't have static IPs at all, because configuring those IPs on some shitty mini LCD display is more effort than entering the router config, checking the MAC of what tries to get an address, and assigning it a fixed one with a hostname.
So you have all your configuration on one single device, the router.

>>106911843
If your server(s) have a public IPv6 address (you can check by typing "ifconfig" in the ssh session and look for a public IPv6 in the list) then just add AAAA records in the DNS zone with the IPv6 address, do the same as you did with the A records (which are for IPv4).

The most horrendous triple NAT (ISP CGNAT, modem NAT + internal NAT) was still less of a hassle to maintain than it is to setup a complex (i.e. more than the typical enterprise tier™ three hosts and two subnets) IPv6 only or god forbid dual stack network. And if your ISP doesn't 100% adhere to the intended IPv6 spec, so not as it is written but the nebulous way some aids riddled monkey intended, it's fucking over anyways since at that point you will have to deal with IPv6 NAT or whatever the IPv6 to IPv6 prefix translation shit was called which is aids on top of Marburg on top of the airborne version of the fucking plague.
It does NOTHING better.
At best it introduces new issues IPv4 doesn't have not even with triple or quadruple NAT and at worst has extremely similar issues to IPv4 but with a million times more complexity.
IPv6 doesn't have a reason to exist, never had one and never will have one.
>b-bb--b-b-but muh intergalactic empire
At that point we will either still use IPv4 with 10^24 layers of NAT or will have moved on to an actual replacement for IPv4 which IPv6 will never be.

Dual stack is easy, I don't know what are you doing.

Yeah that is cancer, ISP sysadmins managing IPv6 exactly the same as IPv4 is why it has such a bad reputation. Switching to another ISP for shit like this should be the normal behaviour.
One of the reasons IPv6 was created is to get rid of NAT and those fuckers brought it back.
>It does NOTHING better.
>IPv6 doesn't have a reason to exist
How about no port forwarding, no confusing internal and external addresses, no split horizon dns, no sni proxies, no hairpin routing, no nat, restore end-to-end connectivity as the IETF originally intended, a simpler configuration process.
>At best it introduces new issues IPv4 doesn't have
The only complex parts are the ones that try to make it backwards compatible with IPv4.

It was always intended to replace IPv4, ever heard of Sunset4? It will come a day that IPv4 will be turned off. It will probably be in 20 or 30 years but eventually it will come.

On the contrary I'm the one pushing for pretty aggressive changes in actual operations. I've actually managed to get corporate to blackball a few companies that would not provide cnc control equipment that would have required hacky workarounds to get online. We quite literally spent an extra 350k on laser equipment for our additive metal machines because the company we wound up going with was willing (excited even) to provide linux support via flatpaks and didn't require the orchestration server to run inside a fucking XP VM with internet access.

The difference between me and the techtards writing specs is that I actually broke it down in terms of dollars and wrote it up in managerial corporate speak. I showed them that the more expensive solution would pay itself off in a few years because of a laundry list of reasons, and while their eyes glazed over when I said the security concerns of the cheaper option were significant, they listened to the rest. About a year later one of our competitors half a state away got hit by encryption malware because of that xp machine plus bad backups and had 2ish weeks of downtime that made them miss deadlines on several major projects. You damn well better believe I brought that up in a strategic meeting. Corporate types love having their decisions validated, and their eyes lit up when they learned about the possibility of pillaging a few high value clients.

Spec writers live in a bubble where everyone is compliant with what is best in theory. Corporate doesn't care about that. They care about dollars, and until you can put things in clear cut terms with hard dollar amounts on the table, business executives will not care about what you have to say. v6 offers nothing to my company beyond additional costs because a ton of equipment won't work with it and even the stuff that does has any one of half a dozen different annoyances making it painful to work with, so any conversation about it is an automatic dead end.

No it's not, you are just dumb. You got uses to something overcomplicated and inefficient, because the ISP gave you a black box router who you just trust blindly.
You can't change anything, because you don't understand it and are unwilling to learn.

We don't even have public ipv6, yet I managed to switch the entire company along with external equipment to ipv6

That's what CGNAT is for.
Rather than banning an IP or and individual customer range, you can't ban the spammer at all, you can just ban everyone using that provider.

>>106915592
You can shorten them though
FC:DB8::1/64
FC:DB8::2/64

69.144.81.7

See the problem? If IPv4 was just extended with another octet or two for 6 in IPv6, it would look like this:

69.144.81.7.71.8

Yes it looks complicated but it's much better than this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

>>106916232

>>106916265
You can not ban an individual behind a CGNAT on IPv4.

>>106916255
>2001:0db8:85a3:0000:0000:8a2e:0370:7334
even this imaginary IPv6 would be written as
2001:db8:85a3::8a2e:370:7334
and because per standard every IPv6 customer has a /64, it would be written as:
2001:db8:85a3::

>>106907869
No, but it sure works as one by blocking glowies and jeets from port-scanning and mapping your entire network.
That's why they hate NAT and keep trying to kill it by pushing the pozzed IPv6 on everyone.

>>106916255
>If IPv4 was just extended with another octet or two
Then you would still have the problem of the utterly stupid IPv6 package structure.
An IPv4 header is anywhere between 20 and 60 bytes with fluff that nobody needs.
An IPv6 header is 40 bytes.
And an IPv6 package allows a higher payload as well, so you have to send headers less often.
You can't even imagine just how much IPv6 simplifies things. It start with the very basics.

No modification of IPv4 can possibly make it good. No matter how much incompetent boomers seeth and cry.

>>106916302
>utterly stupid IPv6 package structure
IPv4*

>>106916289
>That's why they hate NAT
they LOVE CGNAT, anon.
They love NAT so soo much that they implement it on your ISP level as well, just because.
>port scanning
Nigger, IPv6 gives you a whole \64, so someone port scanning you would have to scan 1209239414263882237083648 ports.
Good luck.
Meanwhile every single IPv4 on the whole internet gets scanned by any random discord kiddy every hour.

>>106916269
Where did I claim that?
This was in direct response to banning everyone using the same provider.
Which you can already do in IPv4.

>>106916332
I was pointing out that you have to ban the whole provider and can't ban an individual.
On IPv6 you can do both.
You have less options on v4.

>>106916343
Which doesn't do you any good because spammers can quickly change to a million other IPs since there are so many. So you have to ban whole ranges anyway.

>>106916331
>a whole \64
A good ISP will give you a /48, which is 1.2 septillion addresses.

>>106916279
See it makes no sense, might as well give people a sha512 hash for their address.

>>106913570
jfc now i know why internet used to be good, racism is the only way

>>106916351
You ban the /64. Banning the individual IP makes no sense indeed.
Your banlist becomes an unsigned 64 bit integer. You don't care about half the IP.
And you can run dual-stack with no effort, because the 32 bit IPv4s can still be mapped within it.

Meanwhile what do you do with a spammer on CGNAT who shares the same IP as a hundred legit users? What do you do with a spammer who rerolls IPs with airplane mode on his phone?
The thing, that you think to become a problem with v6, is actually becoming much easier.

>>106916377
>it makes no sense
So 2001:db8:85a3:: is harder for you to remember than 69.144.81.7 ?
Consider that it gets even simpler, the first four digits are almost always the same,
2a03:: is RIPE, so all Europeans.
2001, 2607 and 2600 are ARIN
So you realistically see only those four. So in your random fantasy IPv6, you only have the db8:85a3 to remember.

Do all those simplifications make it confusing for you and you would rather really only have random digits?

>>106916415
>What do you do with a spammer who rerolls IPs with airplane mode on his phone?
How is IPv6 helping there?

>>106916289
>but it sure works as one
it doesn't.

>>106916519
You don't get a new \64 on reconnect.
IPv6 doesn't do any of those funky things and a ISP has no reason to do that.

>>106916533
>You don't get a new \64 on reconnect.
says who?
Why wouldn't the provider just grab a random free IP address for a new connection instead of bothering to keep IPs matching some MAC (which is easy for the spammer to change anyway) or something.

>>106916547
>says who?
The will of the ISP to make money.
It is cheaper not to do it. And there is no reason to.
>Why wouldn't the provider just grab a random free IP address for a new connection
Your connection is already linked to a customer account because the ISP monitors your data usage even when you have an unlimited plan.
Your modem, be it DSL or fiber, already gets a static IP and then builds up a VPN like connection (just PPPoE on DSL) which then gets it the public IP. This still happens even when you have a static public IP and no CGNAT. There is always some customer bound IP in the chain.
Those are the hoops your ISP has to jump through with IPv4, those things don't exist anymore with v6.

>>106916586
>Your modem, be it DSL or fiber, already gets a static IP and then builds up a VPN like connection (just PPPoE on DSL) which then gets it the public IP.
The fuck does my mobile provider know about what my router does with my landline provider?

>>106916606
>but what if its not fiber or dsl but a phone
They already got you mapped with your IMEI. Still cheaper not to rotate a pool.
You are only arguing about edge cases where in the worst case, it will just be as hard with v6 as with v4, while all other benefits still stand.

>>106916679
>Still cheaper not to rotate a pool.
How? Why?
Picking a random ass IP seems to be the simplest possible solution there is.

Maintaining a database with recently disconnected IP assignments and associated identifiers is extra work.

>>106916691
how do you make sure that this random ass IP you picked isn't already assigned to another customer?

idk bro, it seems like you only write for the sake of writing something

>>106916718
>how do you make sure that this random ass IP you picked isn't already assigned to another customer?
Because you do need to know the assignments of active IPs in any case.

But what you don't need to do, is to keep track of the former assignments of disconnected IPs. It is just extra work.

>>106916750
Ever heard of a hash list?
>what you don't need to do, is to keep track of the former assignments of disconnected IPs
You do, its a legal requirement. Which obviously takes up more space when you assign randomly.

>>106906949
>>106907859
They could have just used x.x.x.x.x.x addresses but they had to absolutely overengineer it so every atom in the universe can have it's own IP address

>>106916900
No, it's not.
You just need to append to some write-only log every connect and disconnect and hand it over when police asks for it.

No need to try to match new connections with old assignments and decide on strategies on when to expire old assignments and so on.
It is extra shit you have to do. It's not the hardest thing in the world to do but it's still extra work that the ISP doesn't benefit at all from.

IPv6 is GAY and RETARDED

>>106917589
3 years ago I had my old ISP close out its business because of a catastrophic failure which they didn't disclose.
I switched to another one but saw that i didn't had IPv6, I kindly asked for a subnet and that I was willing to pay extra but they couldn't even give it to me, one of their technicians said all of their network is IPv4 only. A month later I switched to my current ISP that has top tier IPv6 support with a static /56 subnet for regular customers and one or more static /48 subnets for businesses.

so sounds like a skill issue on your end

We need to switch to alphanumeric representation for ipv6. That's 10 alphanumeric 6-bit values [a-zA-Z0-9!*] and 1 hex 4-bit value for each 64-bit half. Then we can name our servers

Tell yourself that when you get a /65 instead of a /64 and want to support Android (which doesn't support DHCP for IPv6).

>>106919196
Also imagine if you got a /64 but wanted to have separate subnets for whatever purpose. lol not supported, you NEED to have a full 64 bits free for SLAAC to work, the only way for that to work is to use NAT64 and rely on private IPv6 addresses, in which case you get the annoyance of NAT and the piece of absolute shit that is IPv6, and at that point just disable it and use IPv4 only.

We have a few legacy machines that require us to go in and manually add SSL certs to them, so we have a couple of self signed internal certs set to expire in the 2060s. In delusional spec lala land this is terrible practice and you shouldn't do that. You should implement some automated deployment to these machines and redeploy your certs every week.

OK... I get that that's what the spec people want, and what we're doing is retarded, but the protocol these machines uses is hacky and you can't just SSH or telnet in. The other major concern is that the eMMCs that they use are /insanely/ fucking bad. If we switch to pushing new certs every month, the flash is going to die and then someone (probably me) is going to have to pull the board out and replace the eMMC. You literally can't get an up to date version of the firmware stored on these pieces of shit, so we'd have to rollback 3 or 4 chips on the boards to the last known full version release just to replace the eMMC holding the certs, then go through and do incremental upgrades to the current version, which has a decent chance of cooking other flash chips on them. Realistically you'd want to pull and replace all of the chips, and probably a bunch of questionably ancient capacitors too while you're at it. Technically doing any of this process would be illegal, but the company that made these pieces of shit hasn't existed for nearly a decade and there's nobody left to care.

Theoretically you could pull a working board now and dump the contents of all these chips, but there ain't a snowballs chance in hell you're going to convince anyone that that's a good idea. The current plan is to just do retrofits the next time something breaks because you literally can't get replacement parts anyways. We're not going to do that until something breaks though because we don't explicitly need all 3 of the machines up at once, and the retrofits will run close to 80k per machine.

And yeah, none of these are ipv6 capable.

>>106919248

I mean if it worked I would want to live in a textbook communist society too, problem is we live in reality and not some Hollywood musical.
It's funny but these discussions always immediately show who's ever worked with this shit before and who's just larping because the ratio of devices capable of modern automated certificate renewal are laughably small.
But don't worry these retards will push for 60 second SSL certificates soon just ignore the fact that stolen SSL certificates are completely irrelevant and the only certificates that ever get abused are the ones used to sign drivers, thank god those come with 30 days forced expiry right?
This shit is just as delusional and disconnected from reality as people insisting companies change their 8-9 digit Dollar value production machines, investing another 8-9 digits on a new machine + the cost of downtime and lost customers + renovation costs (because these things are NEVER drop in replacements) just because hurr durr it relies on W95 or a serial port or because it can't handle the newest faggoty ass change to how many femtoseconds a SSL certificate should be valid for.

Don't forget the part where if you have to crack open a wall to move a piece of equipment in or out nothing is ever the same afterwards. That machine near the hole in the wall that was installed in 1993 will magically stop working perfectly right after it got fresh air for 3 days, even though it was a bone dry middle of July day. Every single test you do says that the machine is operating perfectly normally, but for some reason your reject rate on half your jobs went from .1% to .15, and it's costing you 17,000 a month in waste. Gremlins and ghosts like that are hardly the main reason, let alone the only one, why companies hate change, but it's a solid enough percentage to be worth mentioning.

Things would be so much better if developers and spec writers had to chose between letting a 300CU argon tank roll over their foot without shoes on or use their bullshit on a 10 year old base model laptop for a week. Cool, your a dev working for a company that buys new workstation laptops ever 2 years like clockwork, and now you cannot even conceive of having to worry about pre N wifi devices shitting up your network. Meanwhile in the real world I still have 3 wifi B and G devices that I'm finally getting rid of sometime in December (and realistically it's going to be February). Do you have any idea how fucking happy I was to get it in ink that I'd be able to turn that shit off and crank the minimum broadcast rate up to a sane levels? Literally 70% of our wifi bandwidth in parts of the building is beacons being sent out at dialup speeds because most old hardware will "play it safe" and use the minimum allowable speed for that.

>tfw IPv6 is the entire reason I'm able to homelab at all with my ISP because IPv4 is so locked down on their hardware there isn't even port forwarding in the modem interface.

I am able to use IPv6 with tailscale to access every machine on my network anywhere in the world as if I were home on my LAN, and it's so fast that even over a cell connection in the middle of bumfuck nowhere, loading content feels as fast as loading it locally on the server itself.

Yeah I've seen something like that happen before too.
