Python can do 'threading'.  Look in the doc for the threading
module.  Just create a thread, have the thread do a dns lookup with
socket.gethostbyaddr(ip_address).  When the thread gets the answer it
saves it and sets a flag.

The main loop just goes about its other tasks, checking for the flag
now and then.

There will be details like having the thread timeout after a while, etc.

But prolly 50 lines of code or less.

I put 'threading' in quotes because it is not full blown concurrent
threading, just cooperative multi-taksing on a cingle core.
