Re: Where is the DNS resolution class?

   You can take a look at my DNS resolution classes: 
   <http://rbdns.sf.net>. It supports IP->Name lookups if you format the 
   query correctly (I think its the IP in reverse with ".arpa" on the end, 
   i.e "211.30.96.245" could be looked up with: "245.96.30.211.arpa"; 
   though I might be getting this wrong). HTH,

In the DNS bind source files, the name to address record for xyz.com
looks like:

        xyz.com.                A       1.2.3.4

The reverse direction looks like:

        4.3.2.1.in-addr.arpa.   PTR     xyz.com.
