Perform NSLookup with the InetAddress class

Do you need help with your Java programming?

Click here for instant help with your Java code.

This code example performs a NS lookup and prints out the IP-address along with the host name.
This is possible due to the class java.net.InetAdress which we can instantiate through the static method getByName().

import java.net.InetAddress;
import java.net.UnknownHostException;

/*
* Main.java
*
* @author www.javadb.com
*/
public class Main {

    /*
     * This method performs a NS Lookup
     */
    public void performNSLookup() {

        try {

            InetAddress inetHost = InetAddress.getByName("cnn.com");
            String hostName = inetHost.getHostName();
            System.out.println("The host name was: " + hostName);
            System.out.println("The hosts IP address is: " + inetHost.getHostAddress());

        } catch(UnknownHostException ex) {

            System.out.println("Unrecognized host");
        }
    }
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().performNSLookup();
    }
}
