In computer networks, a reverse DNS lookup or reverse DNS resolution ( rDNS) is the querying technique 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. [1] The process of reverse resolving of an IP address uses PTR records. rDNS involves searching domain name ...

Forward-confirmed reverse DNS ( FCrDNS ), also known as full-circle reverse DNS, double-reverse DNS, or iprev, is a networking parameter configuration in which a given IP address has both forward (name-to-address) and reverse (address-to-name) Domain Name System (DNS) entries that match each other. This is the standard configuration expected by ...
