Re: Turn To Bind-Users For Advice And Help
Hi Anand, > How did you add this zone to BIND? We added this zone through OpenStack Desigante. We sent a HTTP request to Designate for adding a zone. Designate would convert the HTTP request to RNDC command to add zone to BIND.

Re: Determining Which Authoritative Sever to Use
I can't speak definitively for stub zones, but I would assume it works the same as NS delegations or forwarding. A DNS server maintains a listing of smoothed round trip times (SRTT) for each potential destination. It uses the SRTT with the lowest value, and after each successful response all of the SRTTs with a higher value are decremented. This is the self-healing mechanism. Eventually a higher value will be reduced far enough so it is the lowest and it will be used and readjusted. The readjusting will likely make it higher and it would go back to the original server. This is a long winded way of saying all of the servers in the list will take a certain percentage of the overall query volume.

Determining Which Authoritative Sever to Use
Forgive my ignorance if this is a trivial question. Supposing I have an internal IP network (rfc1918) where there atr local caching servers (recursive) which clients connect to and scattered around are several authoritative servers which provide answers for internal only zones. Those internal only zones are defined on the caching servers via stub zones. My question is this; how do the recursive servers determine from the information in the stub zone which name server to query? And, is that the closest (network wise)? Do I need to put anycast into the mix?
