Issue with CIDR sorting.

[mfrakka]

Hi, this is my very first post on GitHub su, please, forgive me any fault. Thank you for your work, I found this module very useful.

But I noticed that the "end.reverse" at line 26 in cidr_facts.rb should be wrong: In this way CIDR mask are evaluated as "wider wins" instead of "tight wins" (using "end.reverse" a CIDR mask /8 take precedence over a /32, for example).
Am I wrong?

Regards.
