plugin handling IP addresses for the Template Toolkit

 Template::Plugin::IPAddr implements an IPAddr class for handling IPv4 and
 IPv6 addresses in an object-orientated way. The module is based on NetAddr::IP
 and works on IPv4 as well as IPv6 addresses.
 .
 You can create a IPAddr object via the USE directive, adding any initial
 prefix as an argument:
 .
 [% USE IPAddr %]
 .
 [% USE IPAddr(prefix) %]
 .
 Once you've got an IPAddr object, you can use it as a prototype to create
 other IPAddr objects with the new() method.
