Rule to block IP without PTR (reverse record)

A number of server-side tracking systems are using Cloud Services Provider IP to deploy trackers. These IPs have **no PTR record**. Just like today Google is rejecting emails from IP without proper PTR record the same logic should be applied by adding an, optional / flag, to perform a PTR lookup and block accordingly like for email.

    Can’t be done with a DNS service. If a browser is given an IP it will connect without the need of DNS lookup.

      you’re not getting the point its to block tagging.myserversidetracking.com (A or AAAA) which doesn’t have. PTR. Any email relay DNS filtering does it.
