Hmm, my understanding was that FQDN means that anyone will resolve the domain to e.g. the same IP address? Which is the case here (unless DNS rebinding mitigations or similar are employed)
but it doesn't resolve to the same physical host in this case since it's a private IP. Wikipedia:
A fully qualified domain name is distinguished by its lack of ambiguity in terms of DNS zone location in the hierarchy of DNS labels: it can be interpreted only in one way.
In my example, I can run nslookup jellyfin.myexample.com 8.8.8.8
and it resolves to what I expect (a local IP address).
But IANA network professional by any means, so maybe I'm misusing the term?
English isn't even the official language of the United States
we don't have an official language.
Various states have official languages (19 states + DC don't have any official language); of these states, English is indeed official, with a few states also recognizing native languages as official alongside English.
Of course that's beside the point, as even calling this sort of racism "thinly veiled" would be far too charitable.
