Java 实例以下实例演示了如何使用 InetAddress 类的 InetAddress.getByName() 方法来获取指定主机（网址）的IP地址：
Main.java 文件
import java.net.InetAddress;import java.net.UnknownHostException; public class GetIP { public static void main(String[] args) { InetAddress address = null; try { address = InetAddress.getByName("www.zhishitu.com"); } catch (UnknownHostException e) { System.exit(2); } System.out.println(address.getHostName() + "=" + address.getHostAddress()); System.exit(0); }}
以上代码运行输出结果为：
www.zhishitu.com=222.73.134.120
