Reverse lookups are possible because of a special domain called the in-addr. arpa domain, which provides a separate fully qualified domain name for every possible ip address on the internet.. to enable a reverse lookup for a particular ip address, all you have to do is create a ptr record in a reverse lookup zone (a zone that is authoritative for a portion of the in-addr. arpa domain). 0 0202 23:13116119217in-addrarpa 16,9 2,96 12,0 0202 In computer networks, a in addr arpa 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. The ptr record maps the in-addr. arpa domain name for the address to the host’s actual domain name. the technique used to create the reverse domain name for a given ip address is pretty clever. it creates subdomains beneath the in-addr. arpa domain by using the octets of the ip address, listing them in reverse order.
