Fast scalable ip range aggregation and summary tool kit. Find intersections across multiple lists of IP ranges, fast. Although similar in functionality to Net::CIDR::Compare, Net::Netmask and NetAddr::IP, Net::IP::RangeCompare is a completely range driven ip management and evaluation tool allowing more flexibility and scalability when dealing with the somewhat organic nature of IP-Ranges. If you have a large number of ipv4 ranges and need to inventory lists of ranges for intersections, this is the Module for you! WWW: https://metacpan.org/release/Net-IP-RangeCompare
