I seem to recall that one of the predecessors of Comcast (Roadrunner? AT&T 
Broadband?) actually assigned real, honest-to-goodness hostnames to each 
customer that were derived from the MAC address.  Maybe that's not the case 
any more.   But James Knott wrote in a recent post:

That's what led me to ask the question.

And by the way, is there a utility that will take an IP address as input and 
return the corresponding hostname as output?  If so, I might be able to use 
that to determine my MAC-based hostname.
