This Windows Server 2022 Tutorial covers how to create DNS (Domain Name System) Reverse Lookup Zone and PTR Record on Windows Server 2022. Domain Name System is a name resolution service that provides a naming system for computers, services, and other resources in the network. The DNS Server resolves computer names or other hostnames to IP addresses and IP addresses to computer names or other hostnames. A DNS zone is the specific portion of a DNS namespace hosted on a DNS server and it contains resource records. The reverse lookup zones are used only for resolving an IP address to a name.
Note: In this Tutorial Active Directory-Integrated DNS is used, DNS servers running on domain controllers can store their zones in Active Directory Domain Services.
Resource records in reverse lookup zones
- Pointer (PTR): PTR record used to resolve an IP address to a name.
- Start of authority (SOA): Start of authority Contains configuration information for the zone, including the name of the primary DNS server and how often secondary servers should be synchronized. There’s one SOA record per zone.
- Name server (NS): NS Identifies a DNS server for the domain. There’s one NS record for each DNS server that has a copy of the zone.
