Ok. I'm coding it right now in a new module but just for testing
purposes (which is easier than modify existing core parts).

Interesting. However, in case the second argument is a pv (i.e.
retrieved from a DB) "equal" operator would not work as expected, am I
right?
This is the reason I'm coding a function "compare_ips" which allow
IPv4, IPv6, IPv6-reference (string or pv).

Maybe another function could be created:   is_ip_in(IP, NETWORK)
