Hmm. I run pfsense, it advertises its own v6 address as a DNS resolver, and I've never had any issues with it breaking. Admittedly, I don't know it isn't just falling back to v4 for a period when the prefix changes. But I did just check and my PC is getting the correct v6 addr of my router as DNS resolver.

At the very least, IPv4 fallback takes a few seconds for each DNS query, and I've experienced it failing completely in some cases (can't recall if I ever figured out why). So regardless it's a PITA when it happens. I tried disabling the option for it to advertise itself as a DNS and instead insert the local IPv4 address in the DHCP options but to no avail, clients still ended up with public IPv6 as main DNS. After a few hours of trying to fix it I just turned off IPv6 again.
