Anyone from years ago could have acquired jfh.com , .net, .org etc. JohnFrankHarry moving company could have registered it YEARS AGO etc. Lol it is who bought and registered that domain first. So if the company JFH E Commerce wants JFH they would have to call the original/registered owner and offer big $$$$ for the DOMAIN NAME. I think or thought you would already know this.
People used to register possible famous domain names and then sell them to a large company that wanted it.
Then you have country-specific China =CN. Japan=JP
It is always good to be cautious and do your own research.
