The look up is returning more than 500 octets, so the DNS
response is truncated and a TCP request is sent rather than
UDP.

More significantly I don't think the reverse lookup is
delegated incorrectly, least wise I can't do a reverse
lookup.

This is just another site that seems to feel the need to add
a new A and PTR record for every domain they host on a
single server, when an MX record and one A/PTR pair would
do. Whilst not against the RFC, this seems pretty pointless
- I postulate Simon's Razor "Do not needlessly multiply
resource records".
