this is still kind of possible, by doing neighbour discovery and querying the host for its hostname with mdns.

In my opinion, this automatic mapping of DNS names to addresess is not part of the IP protocol, and shouldn't be.

"use MDNS for name resolution" works until your machine is reattached to your LAN and your MDNS server thinks your hostname is "in use" and sticks a "-N" at the end of it to "avoid hostname collisions". Though, it might just be Avahi that has this particular bit of brain damage... I haven't paid attention to the behavior of the Macs that I've been obligated to use over the years.

Few people are more sad about this behavior than I am.
