This module overloads hashes so that the key can be a subnet as in NetAddr::IP. When looking values up, an interpretation will be made to find the given key within the subnets specified in the hash. Care must be taken, as only strings that can be parsed as an IP address by NetAddr::IP can be used as keys for this hash. WWW: http://search.cpan.org/dist/Tie-NetAddr-IP/ -Anton
