Hi friends..
Reverse lookup is not working for some ip.

nslookup www.aircell.com gives 74.50.0.200 but
nslookup 74.50.0.200 gives sirona.lunarservers.com

To perform DNS i'm using this code

String tmp = InetAddress.getByName(temp1.getAuthority()).getCan onicalHostName();

where temp1 gets ip address at run time. How to solve this problem?

Thanks..
