That's a great answer. Thanks a lot.
I can believe that Net::CIDR
is the fastest way to do this in Perl.
Unfortunately, it may be too slow. My test program took about 2.5 minutes to
process test file nm5.in. The C program is
about 120-150 times faster.
That's a bummer. I was hoping that there would be a Perl solution
that would be fast enough to be useful.
