cache only vs forwarding

rlebah

If I was using a cache only server is that the same concept as forwarding? Meaning I point all requests to another dns server.

They are all static and forwarding is general where conditional forwarding is domain specific. How does a cache only server differ from forwarding? For a cache only server I install dns and forward all requests elsewhere.

A caching only DNS server will store details of the lookups it has done and provide these when queried whereas a forwarding only server will forward all requests regardless generating traffic to the Primary DNS Server with each name resolution rather than just when the information is not stored within the cached data.

If the caching server does not contain the details requested it will request these from another DNS server (depending how it is setup) and then for each subsequent lookups it can refer to its own cache.

Heres a link I found that explains it further:
