Configure Primary and Secondary DNS zone

Primary DNS Zone

Primary zone in the DNS server is the read/write copy of the DNS database. This means that whenever a new DNS record is added to the DNS database either automatically by the DNS clients or manually by the administrators, it is actually written in the primary zone of the DNS server. One DNS server can have only one primary DNS zone.

Since the primary zone of the DNS server is the read/write copy of the DNS database, it must be kept at a location where it remains physically protected from attacks, and remains safe from internal or external network threats and intrusions.

Secondary DNS Zone

Unlike primary DNS zone, the secondary DNS zone is the read-only copy of the DNS records. This means that the DNS records cannot be added directly to the secondary DNS zone. The secondary DNS zone can receive the updated records only from the primary DNS zone of the DNS server.
