181.242.197.in-addr.arpa. 3600 IN NS douala0.orange.cm<http://douala0.orange.cm>.
181.242.197.in-addr.arpa. 3600 IN NS nsbangui.orangerca.com.
181.242.197.in-addr.arpa. 3600 IN NS yaounde0.orange.cm<http://yaounde0.orange.cm>.

The in-addr currently points to the DNS servers above. Those would need to be changed to your servers or the owners of those servers would need to add the PTR records.

Thank you for your response.
In my case, I have added a PTR record for mail.sami.tn<http://mail.sami.tn> pointing to 197.242.181.69, but it is still not visible from the outside. However, when I test 'dig @0 -x 197.242.181.69', it works. Do I need to request a delegation of 197.242.181.69 to the name servers ns1.sami.tn<http://ns1.sami.tn>?

The in-addr.arpa domain for your IP space will need to be delegated to your DNS servers. That generally happens at the entity that assigned the block. For instance ARIN, RIPE, or APNIC.

Hello, please, I want to know if I need to delegate a range of IP addresses to my authoritative DNS server with my registrar before creating a PTR record or not. In other words, if I want to create a PTR record on my authoritative server (ns1.mydomain.com<http://ns1.mydomain.com>) for mail.mydomain.com<http://mail.mydomain.com> pointing to 41.226.22.50, should the range 41.226.22.0/24<http://41.226.22.0/24> be delegated to my authoritative DNS server ns1.mydomain.com<http://ns1.mydomain.com>?
