What does a Reverse look up zone in the DNS name space resolve?

Explanation:
In DNS, reverse lookups are used to translate an IP address back into the domain name that hosts use, using PTR records stored in a special reverse zone (in-addr.arpa for IPv4, ip6.arpa for IPv6). This contrasts with the usual forward lookups that map a domain name to an IP address with A/AAAA records. So the reverse lookup zone resolves an IP address to a host name.
