Not remotely on the cards with 200+ servers and so on, I'm afraid. Some 
of the servers are too old, I think for IPv6 - SLES 11.

Really I am looking to see if it is possible to turn the internal DNS 
server, bind-internal, into a caching server and help with how to do it. 
Or not to do it if it is a bad idea.
