Reverse DNS not working for new server

[Dawn Connelly]

Root isn't delegating that class C to your DNS server. Your ISP still owns it.
Delegation is pointing to ns.shentel.net. and ns2.shentel.net. According to
ARIN, they own the class B that network is in. If you want to get this fixed,
your best shot is getting the ISP to subdelegate the class C to you. Here's
their contact info http://ws.arin.net/whois/?queryinput=O%20!%20SHENTE
