You want a package but don't want the sender to know your address,
But you know your good friend Proxy from your the good old friend family the Servers.
You tell him what you want, he gets it delivered to his address and then redirects it to you. He could give it to you directly, but to keep the model closer to reality he also sends it to you.
That's how it's done. In computer terms the address is the IP address and the package are lots and lots of IP data packages.
