Hi,

Here is the answer.

We get the hostname of the local ip address. This example is helpful for you.

import java.net.InetAddress;

import java.net.UnknownHostException;

public class staticdemo {

    public static void main(String[] args) {
        try {
            InetAddress localaddr = InetAddress.getLocalHost();
            System.out.println("main Local IP Address : "
                    + localaddr.getHostAddress());
            System.out.println("main Local hostname   : "
                    + localaddr.getHostName());
            System.out.println();

            InetAddress[] localaddrs = InetAddress.getAllByName("localhost");
            for (int i = 0; i < localaddrs.length; i++) {
                if (!localaddrs[i].equals(localaddr)) {
                    System.out.println("alt  Local IP Address : "
                            + localaddrs[i].getHostAddress());
                    System.out.println("alt  Local hostname   : "
                            + localaddrs[i].getHostName());
                    System.out.println();
                }
            }
        } catch (UnknownHostException e) {
            System.err.println("Can't detect localhost : " + e);
        }
    }

}

Thanks.
