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("");
}
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：
=222.73.134.120其他扩展
