Re: Module for working with IP Addresses and Ranges

in reply to Module for working with IP Addresses and Ranges

IMO the canonical tool for this is Net::CIDR. The interface and documentation is kinda clunky in some ways, but it works, and works very well, for both IPv4 and IPv6.

$ perl -MNet::CIDR -e '
  print Net::CIDR::cidrlookup(
    "192.168.1.130",
    Net::CIDR::range2cidr("192.168.1.120-192.168.1.141")
  )'

$ perl -MNet::CIDR -e '
  print Net::CIDR::cidrlookup(
    "192.168.1.180",
    Net::CIDR::range2cidr("192.168.1.120-192.168.1.141")
  )'
