Hi, Some providers will delegate a classless reverse lookup zone to you. That's what you expected.
Some providers will NOT delegate the zone to you - instead they have THEIR name server act as "secondary" to your "master" name server for that zone, i.e., they do zone transfers from your master server to their name servers - and then their name servers answer the queries. >> The customer's CIDR Block: 65.69.21.192/27 << >> If I nslookup 65.69.201.195 << So which is it? 65.69.201.x or 65.69.21.x? http://www.dnsstuff.com/tools/ptr.ch?ip=65.69.21.195 shows that there is a valid Reverse DNS - so why do you want to change it? It also indicates that there is NO delegation from the SWBELL name server to yours.

SWBell would not create a custom PTR but will delegate the reverse zone of their IP's to my name server (which is cool). The problem is I do not think they did it correctly or my NS handles it in an odd way. The customer's CIDR Block: 65.69.21.192/27 Zone in my NS: 192/27.21.69.65.in-addr.arpa (this is from the SimpleDNS Plus reverse zone wizard) Mail server: smtp.gbltx.com [65.69.201.195] If I nslookup 65.69.201.195, all is fine, if I nslookup 195.201.69.65.in-addr.arpa, it only lists NS records (mine and swbell.net's). This is my first time dealing with reverse zones for anything other than /24 CIDR blocks.
