You might also want to look back at the archives for this list around 
late-March/early-April of this year (and possibly earlier). I seem to 
recall there being a similiar question being asked around that time, and 
at least one code snippet posted as well, if memory serves.

Depending on what modules you allow yourself, you may be able to make 
your life a little simpler by using one of the modules that can handle 
IP addresses or address ranges.
