Get IP Address with Adobe Air 2 - air

Question

I'm building an app in Adobe Air 2 with AS3 and need to get the users ip address. From what I understand this code should work but is tracing: "::1" not an ip. Thank you.
var netInterfaces = NetworkInfo.networkInfo.findInterfaces();
var addresses = netInterfaces[0].addresses;
var userIp = addresses[0].address;
trace(userIp);

Answer 1

If you want the real IP and not your localhost, use this:
private function getIp():String{
var netInterfaces:Vector.<NetworkInterface> = NetworkInfo.networkInfo.findInterfaces();
var addresses:Vector.<InterfaceAddress> = netInterfaces[1].addresses;
return addresses[0].address;
}
If you're on Android, don't forget to set permissions:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Answer 2

The code you wrote actually returns the ip adress of the first network Interface it finds.
This is in your case the so called loopback device which is used for local connections
with IP4 the ip adress would be 127.0.0.1
with IP6 the ip-adress is ::1

Answer 3

Try this
var netInterfaces:Vector.<NetworkInterface> = NetworkInfo.networkInfo.findInterfaces();
if (netInterfaces && netInterfaces.length > 0) {
for each (var i:NetworkInterface in netInterfaces) {
if (i.active) {
var addresses:Vector.<InterfaceAddress> =i.addresses;
for each (var j:InterfaceAddress in addresses) {
trace("- Host : " + j.address);
}
}
}
}
