Wait, really? Could you share some examples? Why would they break for a FQDN. Wouldn’t that mean that the root servers aren’t configured correctly for that TLD?
I'm not sure exactly why things break, but as an example: fully-qualifying youtube.com (to youtube.com.) used to break the code that displayed the ads and you could watch ad-free
We also do it in the US, although I feel like it was more common 20-years ago than it is now. For example, here in North Carolina, local school systems are typically “https://[county name]schools.k12.nc.us”
Yeah, our state did that kind of thing 20 years ago, but people get confused with more than x.y, because nobody ever taught anyone the concept that domains are a hierarchy and that periods have a specific role that’s different to slashes, hyphens, etc. So to 90% of people they couldn’t explain how “order.TacoBell.com” is different than “TacoBell.order.com” and as such wouldn’t ever remember what order “k12” “nc” and “us” might go in.
Not sure if sarcastic or not. I think most people don’t think of a URL as an address in the way that a building has an address with a strict hierarchy of meaningful parts. I think people think of it more as an atomic long string of characters that the person who made the site labeled it with just by being the first to claim a certain URL.
