Bring your own IP addresses (BYOIP) in Amazon EC2 and PTR registry

Hello,

I understand that you want to create a PTR record for Elastic IP allocated in AWS.

Since Amazon owns the subnet your Elastic IP was assigned from, they need to create the PTR record for you

Considerations;

a). Before you create a reverse DNS record, you must set a corresponding forward DNS record (record type A) that points to your Elastic IP address[1]. b). If a reverse DNS record is associated with an Elastic IP address, the Elastic IP address is locked to your account and cannot be released from your account until the record is removed[2]

To create a reverse DNS record, see link, https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html#Using_Elastic_Addressing_Reverse_DNS
