Fast IP-in-subnet matcher for IPv4 and IPv6, CIDR or mask
This is a simple but fast pure Perl module for determining whether a given IP address is in a given set of IP subnets. It’s iterative, and it doesn’t use any fancy tries, but because it uses simple bitwise operations on strings it’s still very fast.
All documented functions are exported by default.
Subnets have to be given in “address/mask” or “address/length” CIDR format. The Socket and Socket6 modules are used to normalise addresses, which means that any of the address formats supported by inet_aton and inet_pton can be used with NetSubnet.
