was able to
          configure bind for a particular domain  and name resolution is
taking place.

     But I had another confusion for which I need clarification. It is
nothing on BIND
     but it is on how DNS works....
     The scenario is like this......

     I have configured bind on a machine which is having a public IP but for
a unregistered
     domain "somedomain.com" . The domain name is unregistered because it is
for experimental
     purpose only. In /etc/resolv.conf , I have put the entry as
127.0.0.1because named is running
     on that machine only.


    Now when  I try  to do name resolution for google.com  or any registered
domain name
                          host www.google.com
    on that host , the name resolution occurs fine .

   But if I try to do the same name resolution for any registered domain
name on another machine
   on the  same network , name resolution is not happening for any
registered domains. But name
   resolution is occuring for "somedomain.com" . I have that machine 's
resolver to point to
   the host running name server.

   Please clarfiy whether that behavior is normal. Is name resolution for
registered domain
   name is not occuring because the name server is configured with a
unregistered domain
   name. But then the question comes , why name resolution is happening on
the host running
   the name server even though it is configured for unregistered domain
name.

   Please  clarify my confusion .

   Once again Thanks in Advance


   regards
   zaman
