I am using the unbound library, but not the server.

I think you misunderstand my objective.

Whilst the normal operation of DNS is to discover a record recursively, 
there are some special records that are not part of the normal hierarchy 
and exist uniquely on each DNS server - for example, version.bind., 
version.server., hostname.bind. and id.server. (all chaos txt). 
Basically, I am trying to find the python code using pyunbound that does 
the equivalent the following command:-

dig @[dns-server] version.server. chaos txt

This will return the version of the software that is running on the dns 
server.

Regards,

Chris
