Use case for this feature:
1)In some occasions if you need to allow,block,match specific subnet.
2)I can use recent as a trigger when netfilter rule matches, with mask 0.0.0.0

Example:

If you ping 8.8.8.8, after that you can't ping 2.2.2.10

Could you provide an useful example for this new feature?

I also think you can make this with hashlimit, that allows you to
set the network mask.
