Active Directory-Integrated Primary Zone

Active Directory-integrated primary zone is a type of DNS zone that stores its zone data within Active Directory (AD), rather than in a separate file. Here’s a clearer breakdown:

• Definition:
  A DNS zone where the zone data is stored directly in the Active Directory database instead of a flat file on the DNS server.
• Key Features:
  • Replication: Zone data is replicated automatically along with AD replication, ensuring high availability and consistency across all DNS servers that are also domain controllers.
  • Security: Uses AD security features like Access Control Lists (ACLs) to control who can update or access zone data.
  • Multi-Master Update: Any DNS server that is also an AD Domain Controller can update the zone data, eliminating the single point of failure found in traditional primary/secondary zone setups.
  • Efficiency: Reduces the need for separate zone transfer configurations between DNS servers.
• Use Case:
  Ideal for environments where DNS and AD are closely integrated, such as Windows domain-based networks.
