TIL about ".home.arpa" top-level domain (RFC 8375) for you home LAN domain. I never bothered setting up a domain on my home router. Giving this a try to help name resolution. There are arguments for using a real domain that you've purchased doing something like .lan.myrealdomainname.com so the you don't have to worry about certs and browsing just "works" but I'll give this a try first just to test the waters. FAFO as they say.

  • Guillaume Rossolini on 🌐 : @techlifeweb how about .local?
  • AJ Jordan on 🌐 : @techlifeweb FWIW I use `internal.strugee.net` as my LAN domain... and I have run into problems because strugee.net is on the HSTS preload list (https://hstspreload.org/), and I don't want to maintain a globally valid TLS certificate on any of my networking equipment that's only accessible from my LAN. YMMV. HSTS Preload List Submission
  • Scott Kingery on 🐘 : @GuillaumeRossolini I've read specifically not to use that. Example: https://www.ctrl.blog/entry/homenet-domain-name/ What domain name to use for your home network
  • Guillaume Rossolini on 🌐 : @techlifeweb that is so weird, I thought this was the thing to use? Probably we need to wait a few decades until drivers and firmwares are onto this
  • Scott Kingery on 🐘 : @GuillaumeRossolini I think you're right and it was the thing to use but then some standards changed. Apparently. internal is for businesses and .home.arpa is for home networks. I don't really know enough to know how big of an issue it would be to leave it as .local (probably close to zero) but I decided against it.
  • Guillaume Rossolini on 🌐 : @techlifeweb I don’t enjoy too much the inherent adherence to the US by using .arpa It may have been retrofitted, but who knows
  • Glyph on 🐘 : @techlifeweb Thanks for sharing, I was not aware of this standard! I've been doing the .something.realdomain.example.com approach for some years now and I can't really come up with any advantages of the .home.arpa one, unless you really don't have _any_ domains.
  • Scott Kingery on 🐘 : @glyph You're probably right and I have a domain I should just use but I thought I'd see, for now, how this goes.
