I think the most common gotcha for IP addresses is that they will only appear in intel.log when they are a part of a successful TCP connection. Unsuccessful TCP connections and non-TCP connections will not appear in the log.

Depending on how you generate your feeds the intel linter (https://github.com/packetsled/bro_intel_linter <https://github.com/packetsled/bro_intel_linter>) might be helpful for you.

I have also tried it on the mal-dnssearch feeds with the same results. Is there any particular reason why this would happen? How can I fix it?
