如何获得其他网段中的计算机主机名？

Question

I can get hostname by ip using the method below: (if we are in the same network segment----in case my IP is 10.167.10.2,other's ip is 10.167.10.5)

InetAddress add= InetAddress.getByName(ip);

String hostname=add.getHostName();

but I can't get hostname if the ip in other network segment---in case my IP is 10.167.10.2,other's ip is 10.167.13.5 the return is 10.167.13.5,not the computer's hostname

and when I am using C# ,the class DNS has the methed GetHostByAddress(),I can get every hostname by ip mentioned above using this method.

Our computers are in a domain。 I'm using windows XP,JAVA 1.6 How can I get computer hostname in other network segment? Thank you!
