# A script that compresses/merges/consolidates a list of CIDR addresses.
# It will remove prefixes that are already contained in a 'supernet'.
# It will try to combine smaller subnets into a supernet (ie find both /24's of a /23)
# It will toss out prefixes that are larger than specified (nothing more specific than /24)
