How do I get the hostname of a connected client in java?

I'm writing a server application and I want to get the hostname of the connecting client, how would I go about doing it in java?

clientSocket.getInetAddress().getHostName() keeps giving me the IP address instead of the hostname, what's wrong?

where ClientSocket is an SSLSocket or Socket.

Try getCanonicalHostName() instead - but read the Javadoc, as this is not guaranteed. (You're limited to what is registered in DNS, etc.)
