Yes, there are lots of folks with IPv6 connectivity and v4-only recursive DNS servers. I don't think ISPs will have problems setting aside a handful of IPv4 addresses for authoritative DNS infrastructure to work around this until v6 transport in recursive DNS servers is common enough.
Not really, having your nameservers be IPv6 enabled is a reasonable thing to do. FYI: on comcast I see SERVFAIL, meaning their recursives do not have IPv6 transport. (I know we have that at my employer on our customer-facing recursives). ; <<>> DiG 9.6.0-APPLE-P2 <<>> any www.onlyv6.com. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 54773 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.onlyv6.com.
