Not  necessarily.  The  two are completely separate zone files. Having
authority  to  provide DNS for a domain name to the Internet just sets
up the forward lookup (not the reverse IP).

For reverse  DNS you either 1) have to have been directly allocated the IP
space,  2)  been  delegated  rDNS from the upstream IP provider, or 3)
have the upstream IP provider set up the rDNS for you.
