I've created a public no blacklist DNS list of host names and IP
addresses that should never be blacklisted. Some of them are from my
white list, some from my yellow list, and others are just names and IPs
that you don't want to be on a blacklist. Here's the link that describes
how to use it.

The idea here is if the IP is in this list then you can skip all other
IP based blacklist tests because if found it would be a false positive.
It also reduces bandwidth usage and system load by skipping useless tests.
