What is reverse delegation? what is it used for?
Reverse delegation is reverse DNS record which map an IP address to a name. It is usually maintained by the organisation who receives direct allocations from an RIR. Reverse delegation is achieved by use of the special domain names in-addr.arpa (IPv4) and ip6.arpa (IPv6). It is usually used to validate a forward DNS record, make network troubleshooting more user friendly by providing names instead of IP addresses and also as part of e-mail anti-spam best practices.
