.INTERNAL is now reserved for private-use applications

Can we get .local or .l added for private-use applications too?

.local is already reserved for mDNS.

.local is in this weird state where it's _technically_ not reserved, but most PCs in the world already resolve it with special non-DNS software because of the Bonjour/mDNS protocol.

So you end up with the IETF standardising .local, because Apple was already using it, but ICANN never did much with that standardisation.

I doubt ICANN will actually touch .local, but they could. One could imagine a scheme where .local is globally registered to prevent Windows clients (who don't always support mDNS) from resolving .local domains wrong.

It's reserved per RFC 6762:

> This document specifies that the DNS top-level domain ".local." is a special domain with special semantics, namely that any fully qualified name ending in ".local.

Applications can/will break if you attempt to use .local outside of mDNS (such as systemd-resolved). Don't get upset when this happens.

Interesting fact: RFC 6762 predates Kubernetes (one of the biggest .local violators), they should really change the default domain...
