Add an regexless alternative.

Add an regexless alternative.

This "regexless" alternative just try to implement a more
"generic" solution to the actual "problem".

Please note that this commit will fail tests, because this commit
assume that IPs are not correct rules.

Please also note that the following test will also fail because
the new implementation assume that is actually a parsable
rule. @StevenBlack need to take a decision regarding that one rule.
