Perhaps (if you may classify it as exclusive) .arpa which is still in use I think but you cannot register new domains.
There's also .aero which is pretty exclusive: "only those in various categories of air-travel-related entities may register." - https://en.m.wikipedia.org/wiki/List_of_Internet_top-level_domains#ICANN-era_generic_top-level_domains https://en.m.wikipedia.org/wiki/List_of_Internet_top-level_d...
- L3viathan 7y ago.arpa is in use, but only as an internal detail for reverse name resolution (i.e. looking up the PTR record for 1.2.3.4 queries the server 4.3.2.1.in-addr.arpa)
- WorldMaker 7y agoWhich also yields one of the more interesting backronyms of the internet, as .arpa today is understood to mean "Address and Routing Parameter Area" as opposed to the Advanced Research Projects Agency that was involved in the early internet (ARPANET).
