以下代码:
InetAddress localHost = Inet4Address.getLocalHost();
NetworkInterface networkInterface = NetworkInterface.getByInetAddress(localHost);
for (InterfaceAddress address : networkInterface.getInterfaceAddresses()) {
System.out.println(address.getAddress() + "/" + address.getNetworkPrefixLength());
}
返回:
/fe80:0:0:0:11da:433a:412a:8c23%13/64
/192.168.1.107/128
我的子网掩码是/24，而不是/128。这是 Java 错误吗？
