I've been using NetAddr::IP in a completely different context (ISP IP 
assignment database) for IP address/subnet processing.  I'm not sure if 
it's suitable, but at a glance it seems to have more functionality than 
Net::CIDR::Lite.  Works For Me(TM).

I have no idea what sort of memory overhead it incurs though.
