    You can include some information in router advertisements, likely there will be rfcs for more. Not sure of the full list of stuff you can advertise.

    For sure I’m quite sure I had dns servers configured this way. I’ll check when not on a phone to see what options there are.

      If I recall correctly, you can do stateless DHCPv6 to just hand down a DNS server without also managing the devices’ IP addresses.

        You can, and there’s a specific flag to set on nd/ra to tell the client to get other information from djcpv6. But so far I’ve not made it work and also, it likely won’t work on android.

        Really the way forward is for routers and devices to implement the same options as exist on dhcp. But, time will tell how that gets on.

        This is a weakness of ipv6 but it’s really the lack of widespread implementation that’s behind this. If we were all using it, there would be more onus to get this stuff working.

          What exactly does Google do for Android, then? Hardcode the IPv6 address of their own DNS service, or fall back to pulling AAAA records over IPv4?
