Two questions about dns.log:

- it logs all the answers for each request but only one TTL. Should  
"TTL" be a list of all the values in the corresponding order?

- it doesn't log the type of the answers (A, MX, etc), which seems  
&nbsp;&nbsp;could be helpful?

I thought that was odd myself going through and testing traces.

I haven't ever really been satisfied with the content of that log. It's really hard to represent the DNS request/response pair though considering that you have to weigh data volume with typical use cases. It seems that all most people want (from a security forensics perspective) are the answers that came back from queries and who made the query. The technical details (even response type) matter surprisingly little in most cases. I would definitely like to talk about it more though.

Maybe, but right now at least the TTL is just misleading/confusing I  
think as it's not clear what it belongs to.

We can do that. 🙂
