How to get Client IP address using Java Code Example


In this example, we will take a look at the Java code to get the IP address of the Client computer where this code is executed,

We can make use of the getLocalHost() method from InetAddress class that is present in java.net package.

 */
public class JavaGetIPAddressExample {

    public static void main(String[] args) throws UnknownHostException {
        System.out.println(getLocalIPAddress());
    }

    public static String getLocalIPAddress() throws UnknownHostException {
        InetAddress ipAddress =InetAddress.getLocalHost();
        String ipAddressString = ipAddress.getHostAddress();
        return ipAddressString;
    }

}
