Hi friends..
i tried to find the domain name for ip addresses using this code
String tmp = InetAddress.getByName(temp1.getAuthority()).getCanonicalHostName();
where temp1 gets ip address at run time.it works.but for some ip addresses it is not working:-(
for example:
nslookup www.aircell.com gives 74.50.0.200 But
nslookup 74.50.0.200 gives sirona.lunarservers.com

anyone please tell me how to get the ip address of www.aircell.com
