Seems I have to pay for support now to tell you guys your site is broken, so I hope you at least check the forums.
The DNS reverse lookup for 126.96.36.199 (ns3.wordpress.com) is broken. This is due to a missing/incorrect PTR record. I believe it's part of an RFC spec that you must have a PTR for DNS servers. My registry (isnic.is) detects that your name servers are non-compliant and says they will deregister my domain if it's not fixed in two weeks. Please fix!
The other two name servers (ns1 and ns2) have working reverse lookup, but are technically noncompliant as well because they reference ns3 in the "additional section".
The blog I need help with is gatt.is.
