java编程实现获取服务器IP地址及MAC地址的方法

本文实例讲述了java编程实现获取服务器IP地址及MAC地址的方法。分享给大家供大家参考，具体如下：

已测系统：
windows linux unix

排除127.0.0.1 和 0.0.0.0.1等非正常IP

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;
public class IpUtil {
 private IpUtil(){}
