Enter .https://1024td.com @91.169.91.93 security pron archive()可以获取该节点的所有IP地址
//getNetworkInterfaces()+getInetAddresses
val networkInterfaceEnumeration = NetworkInterface.getNetworkInterfaces()
//枚举进行遍历
while (networkInterfaceEnumeration.hasMoreElements()) {
val networkInterface = networkInterfaceEnumeration.nextElement()
val inetAddressEnumeration = networkInterface.inetAddresses
//枚举进行遍历
while (inetAddressEnumeration.hasMoreElements()) {
val inetAddress = inetAddressEnumeration.nextElement()
//当不是回路地址且是IPV4时
if (!inetAddress.isLoopbackAddress && inetAddress is Inet4Address) {
return inetAddress.getHostAddress()
}
}

::1 IPv6形式，对应IPV4的127.0.0.1
127.0.0.1
fe80::c4eb:7d14:a746:a087%wlan0
192.168.20.20
该方法仅适用于只开启了移动流量未开启WIFI的时候使用，因为我们在遍历并判断是IPV4的地址时，获取到了第一个就直接返回了，而且该方法获取到的也是内网A类地址
while (inetAddressEnumeration.hasMoreElements()) {
val inetAddress = inetAddressEnumeration.nextElement()
//当不是回路地址且是IPV4时
if (!inetAddress.isLoopbackAddress && inetAddress is Inet4Address) {
return inetAddress.getHostAddress()
}
}
当同时连接WIFI和移动流量时，将其打印，可以得到以下地址
10.98.193.41
192.168.137.21
