New "What’s My IP Address" Tool for Multiplayer and Other Uses

Nice addition, thanks for posting.

Just a quick practical note for anyone using this for multiplayer hosting:

1. *Make sure you’re using the Public/WAN IP* (the one the tool reports). That’s the address other people on the internet will need, not your local 192.168.x.x / 10.x.x.x address.
2. If you’re behind a router, you’ll usually still need port forwarding to the PC running the sim, otherwise folks may see the session but won’t be able to join (or you’ll get intermittent connects).
3. If your ISP changes your IP periodically (common with “dynamic” IPs), re-check it before each session.
4. Also worth remembering: some ISPs use carrier-grade NAT, in which case no amount of forwarding will work until you’re on a true public IP.

If anyone’s trying to host and it’s not working, post which sim you’re using (FSX / P3D / X-Plane), what multiplayer method (built-in, VATSIM/IVAO client, etc.), and what exact symptom you’re seeing (can’t see session vs can’t join vs disconnect). I can suggest the correct ports/checks from there.
