ip tracker with VANILLA JS and FETCH API with BEM, RWD, MOBILE-FIRST

I welcome technical opinions about my solution, and recommendations. Feedback is most welcome. I had problems when testing my solution in the browser that has AdBlock extensions installed, as they block requests to the ipify API, as a solution, I implemented an alert informing about with a message. Not being able to think of anything productive that could get around this problem, but I accept solutions, they are welcome too.
