Perl module for manipulating and looking up IP network blocks
Description
Net::Netmask parses and understands IPv4 and IPv6 CIDR blocks (see
<https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing> for more
information on CIDR blocks). There are also functions to insert a network
block into a table and then later look up network blocks by an IP address
using that table.
