The *.home.arpa domain in RFC 8375 has been approved for local use since 2018, which is long enough ago that most hardware and software currently in use should be able to handle it.

RFC 8375 seems to have approved it specifically to use in Home Networking Control Protocol, though it also states "it is not intended that the use of 'home.arpa.' be restricted solely to networks where HNCP is deployed. Rather, 'home.arpa.' is intended to be the correct domain for uses like the one described for '.home' in [RFC7788]: local name service in residential homenets."

The OpenWrt wiki on Homenet suggests the project might be dead: https://openwrt.org/docs/guide-user/network/zeroconfig/hncp_...

Anyone familiar with HNCP? Are there any concerns of conflicts if HNCP becomes "a thing"? I have to say, .home.arpa doesn't exactly roll of the tongue like .internal. Some macOS users seem to have issues with .home.arpa too: https://www.reddit.com/r/MacOS/comments/1bu62do/homearpa_is_...

In my native language (Finnish) it's even worse, or better, depending on personal preference - it translates directly to .mildew.lottery-ticket.

Check the errata for RFC 7788. .home being listed in it is a mistake. .home has never been designated for this purpose.

home.arpa is for HNCP.

Use .internal.

It's ugly and clunky, which is why after seven years it's had very little adoption. Home users aren't network engineers so these things actually do matter even if it seems silly in a technical sense.

Why use that over *.localhost which has been available since 1999 (introduced in RFC 2606)

bravetraveler|10 months ago

From RFC 2606:

  The ".localhost" TLD has traditionally been statically defined in
  host DNS implementations as having an A record pointing to the
  loop back IP address and is reserved for such use
The RFC 8375 suggestion (*.home.arpa) allows for more than a single host in the domain. If not in name/feeling, but the strictest readings [and adherence] too.
