  • You have to find out who is responsible for your public ip address and make the request with them.  My isp is XO and we have a web portal that allows us to manage our block of IP addresses.  You must be able to create this record because your server is not authoritative for that ip address.  Have you tried to add the PTR record with the domain registry that handles your domain names?

     

    I have made changes with our ISP and on Network Solutions for our domain.

  • I had a similar problem and had to contact my ISP to have a reverse DNS setup on our public IP addresses.  I then added a similar entry in our DNS records and everything has worked perfectly since.  I would contact your ISP and ask that they add the PTR records for you.

     

    Hope this helps.

  • I have contacted my ISP but they said they cannot support in this matter. They cannot add Reverse DNS entry.

    What should I do now.
