Answer Wiki:
Depends on your design and/or setup. Here is a rundown on Caching-Only DNS servers. They do not host any zones and are not authoritative for any particular domains. Caching-only DNS servers start with an empty cache and add resource record entries as the server fulfills client requests. Now the information is available in the caching-only server cache when answering subsequent client queries. A caching-only server can be valuable at a site when DNS functionality is needed locally and creating a separate domain or zone is not desirable. I hope this helps explain it a bit more for you.

Davbrown’s answer is correct, but I’m reading your question a little differently.

All name servers (DNS-wise) can be caching servers if so configured – and by default they all are. The only name servers that are typically configured to NOT cache are those that are intended to be the primary authoritative server for one or more domains, and never meant to be queried for any other data. This also protects them from DNS cache poisoning.

The question can be slightly changed to: “Is a caching-only server all I need?” to which davbrown’s response is perfect.

Bottom line here, question-wise, is to determine what it is that you’re actually trying to do. If you care to explore this further, please reply back with more information/questions.

I hope that helps,

Bob

I Agree… with both of the above reply… Caching only server does not store any zone files. Basically what it does is accept client queries .. and ask another dns server for the answer..once it gets the answer it store it in its cache and responds back to the client with the answer… It totally depends in the desing of the network….
