5.1. Caching Only Server

All servers are caching servers. This means that the server caches the information that it receives for use until the data expires. A Caching Only Server is a server that is not authoritative for any zone. This server services queries and asks other servers, who have the authority, for the information needed. All servers keep data in their cache until the data expires, based on a TTL (``Time To Live'') field which is maintained for all resource records.
