Setting Reverse DNS (rDNS) on Dedicated Servers

What is rDNS?

In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. The process of reverse resolving an IP address uses PTR records. The reverse DNS database of the Internet is rooted in the arpa top-level domain. -Wikipedia

  1. Navigate to the main client area (https://www.spryservers.net/clients/clientarea.php)
