Why is the ISP detection (based on my IP address) wrong?
The Internet Service Provider detection shown on whatismybrowser.com is based on a service from a company called MaxMind. They provide a mapping between groups of IP Addresses and the companies who "own" them. This makes it possible to determine which company is providing your internet service.
However, in some cases this database may not be completely accurate and we just want to take a minute to acknowledge that there may be errors occasionally. It's also possible that the company who is technically your Internet Service Provider is essentially "white-labelling" another ISP's service, causing your ISP to be detected as the other company.
It's also possible that the main "carrier" company will be detected as your ISP instead of the actual ISP that you're using.
As with everything on this site; it's just a best attempt and we hope it helped you. We update our database once per week so if it's not being detected accurately at the moment, hopefully it will soon.
