Exactly. If the DNS server(s) handed out by the RG are configurable, then one should be able to configure the IPv4 and/or IPv6 DNS servers.

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?
