2. getByName(String host)

给定主机名的 IP 地址。

3. getLocalHost()

本地主机的 IP 地址。

4.getLoopbackAddress()

返回回送地址

下面给出测试程序：

package com.niepengfei.test;import java.net.InetAddress;public class TestInetAddress {public static void main(String[] args) throws Exception {InetAddress[] inetAddressArray = InetAddress.getAllByName("baidu.com");for(int i=0;i<inetAddressArray.length;i++){InetAddress addr = inetAddressArray[i];System.out.println(addr.getHostName()+" "+addr.getHostAddress());}System.out.println("-----------------------------------------------");InetAddress address = InetAddress.getByName("baidu.com");System.out.println(address.getHostName()+" "+address.getHostAddress());System.out.println("-----------------------------------------------");InetAddress locaAddress = InetAddress.getLocalHost();System.out.println(locaAddress.getHostName()+" "+locaAddress.getHostAddress());System.out.println("-----------------------------------------------");InetAddress loopbackAddress = InetAddress.getLoopbackAddress();System.out.println(loopbackAddress.getHostName()+" "+loopbackAddress.getHostAddress());}}

测试结果如下：
