Here it is – Reverse DNS or rDNS for short. Its goal is to connect an IP address to the domain name with which it is linked. It works in the opposite direction as Forward DNS, with the domain name pointing to the related IP address. DNS hosting firms often offer rDNS as an add-on option. If you do decide to use it, you must also set up a Master Reverse zone and PTR records. Because of them, you will be able to produce proof that the precise IP address and your domain name match.
