I checked it out on my home network, and found that my DHCP server
wasn't sending the hostname back at all.  I am running my own DHCP
server (using the ISC port), so I configured it to do that (with the
"get-lease-hostnames" option).  If you don't run your own server, you
can't do anything about that, so if you want your hostname set to the
correct FQDN, you'd need to do a reverse lookup on the IP address you
found.
