I'm not sure if I'm approaching this problem correctly, so please correct me here.
Suppose an organization runs its own DNS service. The organization wants the following:
- DNS queries by all hosts for external.com should return records that point to proxy.organization.com
- DNS queries by proxy.organization.com should return the real record for external.com
In this scenario, the proxy server should not have a caching DNS server and should not be resolving client queries since the organization has its own DNS servers for the task. Additionally, the extra caching service is another link in the chain that can fail.
Is this a viable configuration (configurable?) under BIND and other DNS servers? I'm having trouble finding the right pages during a search. I'm beginning to think its the wrong approach.
If not, how is this typically handled by an organization?
Thanks in advance.
