Efficiently match IP addresses against IP ranges with C
Description
Net::IP::CMatch is based upon, and does the same thing as Net::IP::Match. The
unconditionally exported subroutine 'match_ip' determines if the IP to match
(first argument) matches any of the subsequent IP arguments. Match arguments
may be absolute quads, as '127.0.0.1', or contain mask bits as
'111.245.76.248/29'. A true return value indicates a match. It was written in
C, rather than a macro, preprocessed through perl's source filter mechanism
(as is Net::IP::Match), so that the IP arguments could be traditional perl
scalars. The C code is lean and mean (IMHO).
