Content Server
However, within the Internet context, "content server" typically refers specifically to a "DNS Content Server." The Domain Name System (DNS) distributes responsibility for managing information needed for name resolution by segmenting domains into administrative units called "zones." Each zone is managed separately, distributing the necessary information for domain resolution across multiple servers.
These distinct administrative domains are called "zones." Thus, a "DNS content server" is specifically a DNS server that authoritatively holds and manages data for a particular DNS zone.
