I'm probably the same. I use a variety of devices, a variety of locations, a variety of connection methods, a variety of VPN servers, and a variety of browsers. I would take a guess at having ~20 different IPs logged against my username.

As others have said, if you are concerned about your IP being logged, either use Tor or a reputable VPN. See https://thatoneprivacysite.net/vpn-section/ if you don't know where to start. Also be aware that if you use Microsoft, Apple, Google, Chrome, Facebook, etc., then a hell of a lot more than just your IP address is being logged.
