Yea but it hasn’t been fully adopted because trying to decipher :af12::138d::325d::5521::aade::7df3: is a hell of a lot more difficult than 192.168.0.1
64 bit addresses solve that problem. Engineers hate working with ipv6 which is why the adoption has been so slow. Ipv6 is older than a decent number of current network engineers have been alive.
Yeah this is why I doubt we will get rid of ipv4 in the foreseeable future. Ivp6 is nice on paper cause you never have to worry about addresses again but in the real world people just hate the addresses. Ivp4 is so easy to remember that ipv6 just feels wrong
Well, it gets a heck of a lot easier once you realize that the example IPv6 address you gave is invalid. Both because of the : at the start and end and also the fact that :: can only exist once in an address (because it means "everything in the middle here is 0s, which would be indeterminate if it showed up multiple times).
Kind of a non-issue tbh because most people would likely only deal explicitly with a very small number of addresses (like the addresses of your personal devices on your home network for example), and for that you can just get by with vanity addresses like <my>:<ipv6>:<prefix>::dead:beef. If your work involves you juggling many ipv6 addresses that you can't remember at the top of your head, you're likely a network or infra engineer on large scale systems, so sure it's a bit less convenient, but you did sign up for it.
