People, I need to find out the "subnet mask" of an IP . How can I do this?

you just type in random numbers between 0 and 255
or you go on /g/

Ask chatGPT or look up a YouTube video, it’s not that hard.
This is literally the most basic shit in networking

I've tried different combinations, but it tells me that it's not allowed or meets the requirements.

and yes, I may not be very smart at networking, but I just don't understand how to find a subnet mask using my IP address.

Try 255.255.255.0

The subnet mask is a code which identifies the range of IP addresses that make up the local network. So, for example, if your PC's IP address is 192.168.0.2 and everything else on your local network has the address 192.168.0.X, then a subnet mask of 255.255.255.0 means "anything where the first 24 bits are the same as this device - i.e. that starts 192.168.0. - is on the local network, while data for anything else needs to go through the gateway".

Wait, you're an employee at an ISP and don't know this basic shit?
