[arm-allstar] Inconsistent IP addresses - node doesn´t connect

[Hotmail]

Hi David,
    One more question… does it make sense that the public IP address changes very rapidly when using a mobile phone hotspot? I’m sorry if I’m asking dumb questions. I am trying to learn more about all of the networking side of things because I am not well educated in this area.
Thanks again,
Nathanael AD8GP

I have tried to see what my public IP address reports back as using three different methods. For my new node each method produces a different result, but for my old functioning node all methods produce the same IP (see tests below).

If you know of an old post somewhere that explains this so that I can go read about it and not take up your time I really appreciate that too!
