     I pretty much had the same reaction. For real projects, I would use 
something like Net::CIDR, and be done with it. It's the kind of problem 
that falls in the same category than XML, CSV and email addresses. On 
the outside, it looks simple enough. Once you begin to poke around, you 
realize the exceptions, subtleties and quirks are much more trouble than 
first expected.  If some other poor sod^D^D^D brave soul took years to 
finely hone a solution for the problem, I don't see the point of trying 
to churn my own.

     Mind you, playing with IP addresses by hand is a good exercise, but 
that's a bit of fun that I don't have time for right now. :-)

Joy,
