Note initial addition of p5-Net-CIDR-Set version 0.10 as
net/p5-Net-CIDR-Set into The NetBSD Packages Collection.

The Perl 5 module Net::CIDR::Set represents sets of IP addresses
and allows standard set operations (union, intersection, membership
test etc) to be performed on them.  In spite of the name it can
work with sets consisting of arbitrary ranges of IP addresses - not
just CIDR blocks.  Both IPv4 and IPv6 addresses are handled - but
they may not be mixed in the same set.
