Perl module for manipulation of IPv4 and IPv6 addresses
This is the Net::IP module for Perl, designed to allow easy
manipulation of IPv4 and IPv6 addresses. Two applications using the
Net::IP module are included: ipcount, an IP address mini-calculator,
it can calculate the number of IP addresses in a prefix or all the
prefixes contained in a given range; and iptab, which prints out a
handy IP "cheat sheet".
