1 We have our own EMail Server Exchange 2016 with a dedicated public IP leased by ISP
2. Currently, we are using ISP's DNS Server but planning to use Premium DNS Service from GoDaddy.
Asking ISP to change DNS record(s) is a troublesome process and we plan to use Premium DNS service from GoDaddy.
I created an DNS zone for my domain and added most of the DNS records on GoDaddy DNS zone but I can't find setting available for "PTR".
suddenly, I realised that GoDaddy doesn't own the public IP of my email server, therefore, it make sense that I shouldn't be able to create Reverse DNS record at Godaddy. (Am I correct???)
My problem is where should I create the PTR record?
(PTR is needed for email server).
(ISP already has the reverse DNS records to resolve IP to hostname. )
What should I do in order to use Premium DNS of GoDaddy?
If I am anything incorrect regarding DNS, please correct me.
