It's built with an object-oriented interface, with functions being methods that operate on a Net::Netmask object. . These methods provide nearly all types of information about a network block that you might want. . There are also functions to insert a network block into a table and then later lookup network blocks by IP address using that table. There are functions to turn a IP address range into a list of CIDR blocks. There are functions to turn a list of CIDR blocks into a list of IP addresses. . There is a function for sorting by text IP address. . All functions understand both IPv4 and IPv6. Matches, finds, etc, will always return false when an IPv4 address is matched against an IPv6 address.
