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?

On my local network I want governance over my devices. I want specific firewall rules per device, so I can, for instance, block YouTube only on the kids devices. I want this to be centrally managed, so configured on my opnsense router. I want all devices to use IP6. Unfortunately none of this is possible.

To setup firewall rules I need DHCPv6, not SLAAC so my IPs on my local network that I manage are well known and fixed. Android devices don't support DHCPv6. And the designers of IP6 were daft enough to set the priority of IPv4 above that of their new protocol. So basically if you have any IPv4 addresses on a device, they'll be preferred by basically all operating systems - because that's what the spec says. So you can't run dual stack in a meaningful way.

TL;DR: IPv6 on a local network has not been thought through at all even though it's incredibly old, it's really immature.
