If a reverse-map file is not included in our DNS configuration then, as normal, the query will pass to The DNS hierarchy continues to see a normal IP address reverse lookup and delegates normally BIND is completely agnostic about line ends (CR+LF or LF) so notepad on windows, for example, will
## REVERSE LOOKUP ##. The Reverse DNS is one of the basic requirements for running some Internet protocols. It is also often used as a spam filter to determine whether the IP address of the incoming message matches an authenticated domain name and to block the message if it doesn’t.
