To create a reverse lookup for a machine called alpha.domain.tld with the address 172.18.10.20:
(note this zone will also used for all reverse lookups for machines in the 172.18.0.0/16 address space)

1. Create a new zone named "18.172.in-addr.arpa"
2. Assign a valid owner
3. Create a Host entry (for 172.18.10.20 aka alpha.domain.tld) of "20.10", type "PTR", destination "alpha.domain.tld"

Save and commit.

To check:

dig @<dns server address> PTR 20.10.18.172.in-addr.arpa

should return alpha.domain.tld
