java获取本机物理ip地址吗_Java获取本机所有ip地址

java获取本地ip的两种方法

第一种：

InetAddress inetAddr;

inetAddr = InetAddress.getLocalHost();

System.out.println(inetAddr.getHostName());

System.out.println(inetAddr.getHostAddress());

第二种：

Enumeration netInterfaces = NetworkInterface.getNetworkInterfaces();

InetAddress ip = null;

while (netInterfaces.hasMoreElements()) {

NetworkInterface ni = (NetworkInterface) netInterfaces

.nextElement();

// 网卡描述

String displayName = ni.getDisplayName();

System.out.println(displayName);

ip = (InetAddress) ni.getInetAddresses().nextElement();

System.out.println(ip.getCanonicalHostName());

System.out.println(ip.getHostAddress());

}
