PTR records are not done by your DNS host; they are done by whoever owns that public IP address block - in this case your ISP. &nbsp;It's done a bit differently since it is a reverse entry of the address the ISP owns.

We recently needed to add a PTR record. So I called our DNS hosting company. They said I would need to call our ISP. I called. Then our ISP did it very quickly.<br />
I did not have the impression that our ISP had contacted our DNS hosting company for this. So I am very curious how our ISP added a PTR record in our DNS without knowing the login credential to our DNS hosting? Or in other words, does an ISP have to login the DNS hosting in order to add a PTR record? If not, how can they do it?<br />
<br />
Thanks<br />

How could the ISP add a PTR record for us without knowing our DNS hosting login?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances.
