Since you obscured the IP address, can I assume you are talking about the
reverse lookup on your public IP address?
Unless your ISP, who actually owns the IP address, has delegated the reverse
lookup to your DNS server, your DNS server will not be queried for the PTR
record.
You will need to contact your ISP, or whomever is Authoritative for the
reverse lookup, to delegate it to you or create the PTR for you.
