Only a few years ago in college (2014?) I lived in a fraternity house and frequently had to track people down for updates on projects.

Turns out Apple devices did (or still do?) expose the DNS hostname with a format like: JAKES-iphone-some-guid

I created a little script to ping the local network for known hosts, return a reverse lookup of the hostnames, parse the name from the iPhone hostname, and update their status in little list of who was in the building, in case I needed them for something.
