I use a ip link checker - to verify the vpn is working like it should. They're a dime a dozen but this one is the one that showed up first on my search.
basically, you download a unique-to-you magnet torrent, and then the torrent / website will tell you what ip is being shown to the outside world. if you leave it in your client you can see at a glance what ip you are actually using in your client.
