I was hoping that there would be a Perl solution that would be fast enough to be useful

Of course if you patched the module with XS and your C code there would be :-) Just a random thought to increase your workload for the benefit of everyone (except perhaps you).

Says tachyon:

Not really. The C program is a complete program that solves this one specific problem. There's nowhere in the Net::CIDR interface to 'patch'; the module doesn't do what this program does, and this program doesn't implement any of the functions that Net::CIDR does.

Even if I did put it in, there wouldn't be any benefit. At present, you could compile my program and then use:

#!/usr/bin/perl
system("mjd-merge-blocks inputfile > outputfile");

Then you could call it a "Perl solution", but it wouldn't really be one. Hacking my code into Net::CIDR wouldn't be a "Perl solution" either.
