I have implemented it by you using
instead of
in the condition in a line in a ruleset.

I can see how this might be useful should you be needing to test against 
a dynamic IP address, in which case you will have a DNS PTR record but 
no DNS A record.

This will hopefully solve your problem nicely.

It will be in the next release.
