A DNS zone is a part of the DNS namespace that is managed by a single administrator and contains DNS records for domain names within that zone.
When a domain controller (Active Directory Domain Controller) is set up, the following DNS zones are created:
-
Primary zone — a zone that corresponds to the Active Directory domain name, for example, example.com. It stores records necessary for AD operation, including SRV records that help clients locate AD services.
-
Reverse Lookup Zone — a zone that allows determining the domain name by IP address. Usually, a reverse lookup zone is created for a subnet, for example, 192.168.1.x.
-
AD-integrated zone — a DNS zone stored in the Active Directory database, which ensures replication of DNS records along with AD data between domain controllers.
Thus, when a domain controller is installed, an AD-integrated DNS zone is created, which provides name resolution within the domain and supports Active Directory services.
