I don't know if it is still required but hostnames used to require a minimum of two chars and the first shalt not be an integer. Given that DNS does not put a proper boundary on host/domain, that might extend to your top level ... thingie.
However, there is absolutely no technical reason that I can think of that precludes u@x. In the end DNS query -> DNS answer. Given that say, PowerDNS has LUA built in, I can make it respond with "my little pony's stable is in {random_country}" - to A record requests, which might make the requester a little queasy!
Bugger standards, they are so 1990s!
- esperent 1y agothe first shalt not be an integer I recently came across the 3.ie domain so I guess that's more of a guideline than rule.
- AStonesThrow 1y agoI believe that the rule has been deprecated due to better parsing. In the mid-90s, 3M was a customer of the ISP I worked for. Unable to procure the domain name “3m.com” they settled for the alternate “mmm.com”: mildly hilarious considering their lines of business.
- leslielurker 1y agoFunny to see mmm.com still works, but it loads up the 3M site without its stylesheet and shows a 404 page. I guess the redirect has been forgotten about at some point.
