How it works

Thanks to our patented S.T.U.P.I.D. technology, our machine learning algorithm is able to determine with 100% accuracy what your IP address is not. This feat is made possible by combining the headers sent by your internet browser and the geolocation data provided by the various ISPs in your country of residence, then ignoring them with the utmost care to give you the most approximate result possible.

About your privacy

WhatIsNotMyIp teams respect privacy, and guarantee that your IP will never be transmitted to third parties, partly because we have absolutely no idea what the fuck we are doing.
