Reverse DNS lookup setup for multiple IPs

0

I've associated one of my EC2 Elastic IP addresses with a reverse DNS record. Will this suffice for all the IP addresses which route to my instance, or must I do this for each IP address? If required for each IP address, where does this get done?

HI, When you associate a Reverse DNS record, it applies only to that specific Elastic IP address. It does not automatically propagate to other IP addresses that may route traffic to your EC2 instance. if you have multiple Elastic IP addresses associated with the same instance, you would need to set up a separate Reverse DNS record for each Elastic IP address.
