I'm with you with similar setup. But I think this is mostly about being able to configure your border router with (a) the right DNS server address for DHCPv4 and (b) the right DNS server address for RFC 5006/DHCPv6. Is your problem that you don't get to do (b)? Or do you skip (a) as well, and then rely on local multicast naming discovery?

Wanted to share something here to get some feedback and to determine if this is something that is in scope for HOMENET. Consider the following: * dual stack home network * private IPv4 * global IPv6 * local DNS that resolves local hosts, this data is not available authoritatively on the Internet My home router supports RFC5006 (not sure the RFC was revised when the router firmware was developed). There is an IPv6 DNS server configured on the router which is transmitted in the router advertisements. A host on the network supports RFC5006. When the host attempts lookups for local resources using the global IPv6 DNS server address it recurses to the Internet and never gets the answer it expects for the local network resources. The client resolver also never attempts to contact the local, private IPv4 DNS server since the IPv6 DNS is technically responding. Explicit DNS queries to the local, private DNS servers work but this not really usable. Ultimately I had to disable DNS over IPv6 to ensure local and Internet resources are resolvable. In this case the local IPv4 DNS server is a separate server, frankly I am not sure if having them be the same device ie the home router would make a difference. I suppose this would depend on the router's DNS capabilities. It seems to me that this situation is bound to crop more up as IPv6 deployments increase.
