The ApacheSW Commons NetS library has a WhoisClient class that makes it very easy to connect to a WhoisW server and query it.

The WhoisLookup class demonstrates the use of WhoisClient. We make a connection to "whois.enom.com" using the connect() method, and then query the Whois server using the query() method with our query string. The query() method returns the results in a String, which we then display.

WhoisLookup.java

package test;

import org.apache.commons.net.WhoisClient;

public class WhoisLookup {

	public static final String WHOIS_SERVER = "whois.enom.com";
	public static final int WHOIS_PORT = 43;

	public static void main(String[] args) throws Exception {

		String nameToQuery = "abcnews.com";

		WhoisClient whoisClient = new WhoisClient();
		whoisClient.connect(WHOIS_SERVER, WHOIS_PORT);
		String results = whoisClient.query(nameToQuery);

		System.out.println(results);
	}
}
