However there are many servers set up in NZ where the forward and reverse DNS do not match, or there are no PTR records at all. After all this is outlined in RFC 1912 (section 2.1) and RFC 1033
See also draft-ietf-dnsop-reverse-mapping-considerations-06, which google knows how to find and which is currently in working group last- call (I think).
