【Java】使用 java.net.InterfaceAddress 获取网卡信息

作者:鉴客 / 发布于2011/1/10/ 1116

InterfaceAddress 类表示一个由名称和分配给此接口的 IP 地址列表组成的网络接口。它用于标识加入多播组的本地接口。接口通常是按名称（如 "le0"）区分的。

import java.net.InterfaceAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.List;</div>
<div>public class NetworkParameterDemo {
 public static void main(String[] args) throws Exception {
 Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces();
 while (en.hasMoreElements()) {
 NetworkInterface ni = en.nextElement();
 printParameter(ni);</div>
<div> }
 }
<div> public static void printParameter(NetworkInterface ni) throws SocketException {
 System.out.println(" Name = " + ni.getName());
 System.out.println(" Display Name = " + ni.getDisplayName());
 System.out.println(" Is up = " + ni.isUp());
 System.out.println(" Support multicast = " + ni.supportsMulticast());
 System.out.println(" Is loopback = " + ni.isLoopback());
 System.out.println(" Is virtual = " + ni.isVirtual());
 System.out.println(" Is point to point = " + ni.isPointToPoint());
 System.out.println(" Hardware address = " + ni.getHardwareAddress());
 System.out.println(" MTU = " + ni.getMTU());</div>
<div> System.out.println("\nList of Interface Addresses:");
 List<InterfaceAddress> list = ni.getInterfaceAddresses();
 Iterator<InterfaceAddress> it = list.iterator();</div>
<div> while (it.hasNext()) {
 InterfaceAddress ia = it.next();
 System.out.println(" Address = " + ia.getAddress());
 System.out.println(" Broadcast = " + ia.getBroadcast());
 System.out.println(" Network prefix length = " + ia.getNetworkPrefixLength());
 System.out.println("");
 }
 }
}

试试其它关键字

　网卡信息　

同语言下

可能有用的
