package com.devnp;

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

public class IPTest {

	public static void main(String[] args) {
		
		try {
			InetAddress ip = InetAddress.getLocalHost() ;
			
			System.out.println("Host Name : " + ip.getHostName() + " Host IP : " + ip.getHostAddress());
			
		} catch (UnknownHostException e) {
			e.printStackTrace();
		}

	}
}

结果：
Host Name : duliu Host IP : 192.168.56.1
