Reverse DNS: A process of resolving an IP address back to a domain name. Unlike the standard (forward) DNS lookup which translates a domain name into an IP address, rDNS does the opposite. This can be used as a simple form of verification, as it can be slightly more difficult for a malicious party to ensure a proper rDNS configuration compared to spoofing DNS responses.
