People still working in IT, thoughts on IPv6? (lemmy.world)

Now currently I'm not in the workforce, but in the past from my work experience, apprenticeship and temp roles, I've always seen ipv4 and not ipv6!

Hell, my ISP seems to exclusively use ipv4 (unless behind nats they're using ipv6)

Do you think a lot of people stick with the earlier iteration because they have been so familiar with it for a long time?

When you look at a ipv6, it looks menacing with a long string of letters and numbers compared to the more simpler often.

I am aware the IP bucket has gone dry and they gotta bring in a new IP cow with a even bigger bucket, but what do you think? Do you yourself or your firm use ipv4 or 6?

I think djb was right, over twenty years ago: The IPv6 mess

The IPv6 designers made a fundamental conceptual mistake: they designed the IPv6 address space as an alternative to the IPv4 address space, rather than an extension to the IPv4 address space.

There was an alternative proposal that was backward-compatible with IPv4, but I’ve forgotten the name now.

Oh man, that would have been so great. Think of all the networking stacks that could have just been silently upgraded. Just some letters/numbers appended to the front or back. If you only get x bytes then prepend with zeroes. Adoption would have been mostly transparent.

Yup. For those that don't know, that's essentially how utf-8 works -

I'm gonna guess...... IPv5

That wasn’t it. I wanna say “IPvX”, but my web search comes up empty, so it must have been something else.

I think IPv4+ is what you’re thinking of
