Reverse DNS and BIND, 19 October 2023
A DNS lookup takes a name and returns an IP address; reverse DNS does the opposite, and provides a name when given the address. Greg Choules, ISC Support Engineer, explains what reverse DNS is and how to set it up in BIND. (The slides are available at https://www.isc.org/docs/ReverseDNSpr...)
