FYI - Comcast has dual stacked enabled recursive name servers, see the following web site: http://dns.comcast.net/dns-ip-addresses3.php John On 4/23/10 8:42 AM, "Jared Mauch" <jared () puck nether net> wrote:

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.
