Thank you all for the suggestions.
Prefetch sounds like a good solution and still provides the designed behavior
for integrity. I see Bind 9.10 introduces “prefetch” and I will look into it.
Until we change or upgrade, a simple solution may be our own prefetch (periodic
lookup) of popular CNAMES
I fully agree.
Now, please understand the following question has been asked of me and I fully
realize the implications and that it is just not a good idea. I will gladly
forward the suggestions to my peers (and bosses).
Is there any way to accept the first response (CNAME with IP) and not perf

I'm sure there's a good, simple reason for this, I just can't seem to find the
answer searching on the Internet.
Why does named perform a lookup for the A record when its IP is returned with
the CNAME in the first answer?
Using dig, I find play.google.com is a CNAME for play.l.google.com.

Is your firewall Cisco based?
There is a known "default" setting in Cisco with respect to packet size
for DNS. Our network guys run into this anytime they do an upgrade,
etc. and have to go in and update the setting.

It is my experience the client hits the views in order (top, down) until
an ACL allows it. Once an ACL allows it in a view, it goes no further.

I've been using multiple views and servers successfully for a while now.
I hope the following helps...
To transfer zones to and from specific views, you can use keys,
"match-clients" and "server" declarations to control access and
transfers.
Setup keys for each view.

It is a bad idea, although I know (from experience) it will work for
static zones. One problem is you need to remember to reload the zone in

Have you looked at the logs?
You may need to change the debug level with rndc. You can also set it
when starting bind - named -d debug-level.
Debug level 5 - "Captures the view being used in order to answer a
request".
Have you verified the two views which are being transferred to make sure

Is it possible named was killed and restarted without
the /etc/init.d/named script?
The script looks up the process ID from /var/run/bind/run/named.pid (on
Debian) and if the PID doesn't match, the script can't stop named.
You can cat /var/run/bind/run/named.pid and compare the PID to what you

I would like to resolve dns.ourdomain.com to a list of our DNS server
names and possibly their IPs.
As we use many DNS servers (and or views) for our different development
environments, it would be very helpful for the developers to easily find
the name and IP of the proper name server to use.
