Reverse lookup not working

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..

There is nothing wrong with that reverse lookup.
More then one name can map to an ip address, and is rather common.
Example:
> google.com
Non-authoritative answer:
Name: google.com
Addresses: 72.14.207.99, 64.233.187.99, 64.233.167.99

> 72.14.207.99
Name: eh-in-f99.google.com
Address: 72.14.207.99
