I'm very new to all this; I was able to cobble together a CIDR-to-IPs calculator in JavaScript, but going this other direction seems much harder, and far more confusing. If you know anything about Perl, you can use the port: /usr/ports/net/p5-Net-CIDR-Lite to convert back-and-forth. For documentation, I referred to: http://search.cpan.org/dist/Net-CIDR-Lite/Lite.pm -d
