These are TLDs not nominally tied to a specific country like the classic .com and .net, or more recent ones like .work or .crypto. But they weren't banned because ICANN hates fun or convenience.

And if your PC thinks it's talking to a dotless domain on your local private network, but is actually connected to a public domain with the same name, that opens the door to myriad potential security holes.
