Yup indeed. That's why it advertises both dhcp and slaac

I use openwrt on my home network which uses dnsmasq for dhcp. It can give a static suffix which just works with the global prefix on the interface and the site local / ula prefix it uses

Weird! Though I guess a lot of these would be sitting behind load balancers / reverse proxies anyway (so ipv4 is fine) and unlikely to up and change isps very often? Lol

If I had to, I'd be trying to add an extra cidr to one of the options listed at https://kubernetes.io/docs/concepts/services-networking/dual-stack/#configure-ipv4-ipv6-dual-stack But as you say, probably doesn't work!

Indeed, that's correct ula usage, but shouldn't need nat rewriting. The global prefixes just need to be advertised by RA packets

[–] Thiakil@aussie.zone 1 points 4 months ago

Not sure on the history of that. It would make things like that easier

Even if you give it multiple ip6 cidrs to allocate?

[–] Thiakil@aussie.zone 1 points 4 months ago

It certainly looks like you can give it a prefix to assign out, possibly even multiples

Instead of nat and port forwards that rewrite, your firewall is set to only forward specific traffic, exactly how'd you'd configure outbound forwarding on a nat network (but opposite directions)

Open forwarding is a router, not a firewall

Also for routing table reasons. Ipv6 needs to use prefixes to do link aggregation or it just gets too bjg

Address space is so huge that iirc the only global addresses in use are 2xxx::

Its so huge that it's not needed to use anything else is the goal as far as I see. If it starts with 2, it's global.

Ehh, I've seen both. Perhaps not in a home router context though, never really bothered to check
