IN AAAA ;; ANSWER SECTION: ns2.v6.mydyndns.org. 86315 IN AAAA 2607:f590:f2::2 Here is a snippet from a recent newsletter from DYNDNS http://www.dyndns.com/news/newsletters/36.html <snippet> As part of this IPv6 initiative, we have recently added an IPv6 test server â ns2.v6.mydyndns.org â for Custom and Secondary DNS customers. Entering this nameserver into the delegation for a domain will allow visitors to perform DNS queries over IPv6, making DynDNS.com one of the first DNS providers to offer this functionality. After thorough testing, we will upgrade all of our DynDNS.com and Dynect Platform nameservers to provide dual stack IPv4/IPv6 connectivity. If you are a Custom or Secondary DNS customer and youâd like to give our new IPv6 test server a spin, you can check out our brief tutorial for setting it up here ( http://www.dyndns.com/support/kb/ipv6_with_custom_secdns.html ). </snippet> I happen to be a DYNDNS Custom DNS user, so I will see how things work with the test server. ---Dave Horn
