Thanks, didn't even know it existed.

> I didn't see a specific RFC that reserved .lan

There is no RFC AFAIK, but it has certainly seen some adoption over the past decade. Mikrotik devices use `router.lan` as a default domain name for their routers, for instance. Home labbers on YouTube seem to like to use `.lan`, too.

Would it be fair to think there is a chance `.lan` might get an RFC of its' own given the popularity? Or that's completely irrelevant in case with RFCs? Hard to tell what's the reasoning there - `.home.arpa` seems excessivly long and inconvenient.

Would be a real shame and a bummer if `.lan` ends up becoming public :')

I agree it would be great to get some of the vendor pushed / common domains put into an accepted standard.

In my interaction with IETF standards they are created / implemented in two ways:

  1. They set the forward direction for a new technology before it is wide spread.
  2. They wait for a technology to become popular / accepted and start to set standards from that baseline.

I doubt .lan, .local, .home, etc will either become public or a standard just based on existing devices that default to these domains and documentation or books that might reference them as example domains.
