I’m trying to understand how reverse DNS works and why I can’t find clear explanations. I need to know how the DNS server identifies the correct authoritative server for a given IP address in a reverse lookup.

Reverse lookup zones are given a specific address space. This often looks like an IP in the format x.x.x.in-addr.arpa. These zones connect to name servers and have an SOA record. The address spaces follow a reverse format. When DNS examines an address, it directs it to the appropriate zone based on its location, then proceeds to the linked name server that holds the PTR record.

It relates to how A records connect to an IP within the same block as the reverse DNS entry. The tool you're using for DNS is likely a DNS client or server software. Thank you for your prompt reply.

It is linked through PTR records. When you configure the reverse lookup zones before adding A records, you can enable automatic creation of the corresponding PTR record in the appropriate zone. PTR records function differently from A records—they act as their inverse. This feature is part of the DNS Manager within the DNS role on a Windows server.
