There isn't an easy way to do that, and there wasn't before. If 
resolving a non-routable IP happened to work for you previously that was 
just luck, not something to rely on. The most reliable method would be 
to use something like https://www.whatismyip.com/ that tells you the 
public IP you are using to make a connection.
