How would Facebook do that? They scan all likely local ranges for what could be your phone, and have a web server running on the phone? That seems more like a problem of allowing the phone app to start something like that and keep it running in the background.

Webrtc allows you to find the local ranges.

Typically there are only 256 IP's, so a scan of them all is almost instant.
