JAVA的IP

JAVA使用IP只有方法，没有类。这个方法名是：InetAddress。

.getAddress()//获取地址
.getHostAddress()//获取ip
.getHostName()//获取主机名
.getCanonicalHostName()//获取规范主机名

package IP;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class TestInetAddress {
    public static void main(String[] args) {
        InetAddress inetAddress = null;
        try {
            inetAddress = InetAddress.getByName("www.baidu.com");
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        System.out.println(inetAddress);//包括地址的名和ip
        System.out.println(inetAddress.getAddress());//获取地址
        System.out.println(inetAddress.getHostAddress());//获取ip
        System.out.println(inetAddress.getHostName());//获取主机名
        System.out.println(inetAddress.getCanonicalHostName());//获取规范主机名
    }
}
