Sounds like a good use for Multicast DNS?

Sounds like adding yet another potentially exploitable service listening on every host? Swell!

Seriously, I have yet to see a good tutorial how to herd IPv6 LAN with reliable local DNS, as is usual with IPv4. Everything is just handwaved away "nah, zero configuration". The reluctance to adopt it could stem from that.

Dude, it actually is zero configuration lol. My devices assign themselves an IPv6 via SLAAC, and they are reachable from other devices via devicename.local.

Macs and iPhones have relied on mDNS for years. Windows supports it. Android supports it since 2022. Linux has avahi.

If people could look a little further than the tip of their nose, they’d realize how much easier it’ll be to explain to people to just type in alices-iphone.local instead of trying to find the IPv4 address first.

..until another Alice joins the network with her iphone. There are plenty of valid reasons to manage names centrally and configure addresses explicitly, but no I'm supposedly a dinosaur that is supposed to get extinct finally :(

It will rename itself to be alices-iphone-2.local

which one?
