How To Get IP Of Website

This post shows the steps and code required to get the IP of a website. It expects a valid website URL in order to query the same to get the IP.

The basic code to get the IP of a website is as shown below.

// Stores the site URL
String siteUrl = "https://www.google.com";

// Convert the String to URL
URL url = new URL( siteUrl );

// Create address object
InetAddress ip = InetAddress.getByName( url.getHost() );

// Get the IP
System.out.println( ip.getHostAddress() );

Below is the fully implemented and tested code to show the IP of the given website URL.

package networking;

import java.net.InetAddress;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.UnknownHostException;

public class ShowIp {
	public static void main( String args[] ) {

		// Stores the site URL
		String siteUrl = "https://www.google.com";
		ShowIp ipUtil	= new ShowIp();
		InetAddress ip	= ipUtil.getWebsiteIp( siteUrl );

		// Print the address
		if( null != ip ) {
			System.out.println( "The IP Address of given site URL - " + siteUrl + " is: " + ip.getHostAddress() );
		}

		// Show error
		else {
			System.out.println( "IP not found for given URL" );
		}
	}

	/**
	 * Get and return the IP address using the given Web URL.
	 */

	public InetAddress getWebsiteIp( String siteUrl ) {
		InetAddress ip = null;

		try {
			// Convert the String to URL
			URL url = new URL( siteUrl );

			// Create address object
			ip = InetAddress.getByName( url.getHost() );
		}

		// URL not formatted
		catch( MalformedURLException e ) {
			System.out.println( "Invalid URL found" ); 
		}

		// Host not found
		catch( UnknownHostException e ) {
			System.out.println( "Host not found" );
		}

		// Returns address object
		return ip;
	}
}
