Similar feel, no need to understand german. Its a calculator by a newspaper to figure out if you would be considered middle class, but the whole thing is paywalled… zeit.de/…/soziale-ungleichheit-einkommen-armut-re…
IP adresses are pretty edge case yeah. I dont know if that should even be supported. The “example.com” does actually work tho, its just if you only include “.co” in your selection, it doesn’t recognize it as a URL even tho .co is the national TLD of Colombia. But all that really needs to change is to support all existing TLD’S and maybe IP addresses if there is community interest in it.
