package net;

import java.net.InetAddress;

public class iptest {

	public static void main(String[] args) throws Exception {
		//根据计算机名获取计算机的ip地址		
		InetAddress byName=InetAddress.getByName("Win7-2017CVNAPK");
		System.out.println("计算机ip是："+byName);
		 
		
		//返回本地主机,只能获取本地机主信息
		InetAddress localHost=InetAddress.getLocalHost();
		System.out.println("本地机主信息："+localHost);
		
		//基于第2个方法
		String hostName=localHost.getHostName();
		System.out.println(hostName);
		String hostAddress = localHost.getHostAddress();
		System.out.println(hostAddress);
		//总结：InetAddress对象包含了ip相关的操作
