This document explains how reverse DNS works and how to configure it for your zone. Further down the tree, there are delegations for the /8 blocks that IANA allocated to the RIRs, the allocations that the RIRs gave to the address holders, all the way down to the individual IP addresses and names that you have configured for your Internet-enabled hosts.The process of reverse resolving an IP address uses the pointer DNS record type (PTR record).As we would need to use CSV file as in previous method (DNSShell module for Windows Power Shell), we will reuse it.Computer networks use the Domain Name System (DNS) to determine the IP address associated with a domain name. Reverse DNS Troubleshooting The reverse DNS database of the Internet works with a hierarchical tree of servers, just like forward DNS.
If so, delegation will be propagated to the DNS by the RIPE NCC's name servers.This process is also known as forward DNS resolution. It is rooted in the Address and Routing Parameter Area (arpa) top-level domain of the Internet.
