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

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.
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?

Thanks
Jack

Your ISP doesn't actually create this record through your DNS hosting company. As the IP address itself belongs to your ISP, they are the ones that have the necessary access to create the PTR record. See these articles for more info:

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.  It's done a bit differently since it is a reverse entry of the address the ISP owns.
