Amazon AWS - How can I change the Private IP of a Network Interface linked to RDS

Question

I created an RDS DB Instance linked to a VPC.

This created a Network Interface and automatically assigned an internal IP: 10.0.10.65

I want to change this IP address to 10.0.10.15

How can I achieve this?

Users do not have control of the IP address assigned to RDS instances. You can choose the subnet but cannot assign a static IP address like you can for EC2 instances in a VPC.

Unlike EC2 instances, allocating a private ip of an RDS instance is not possible, this has been answered in this question.

The recommended method to access an instance is through its endpoint:

Please note that, we strongly recommend you use the DNS Name to connect to your DB Instance as the underlying IP address can change (e.g., during a failover).

If we use the DNS name and a EC2 instance access it, will the call go through the Internet or will be local as a call with the private IP would be? – vIceBerg Feb 26 '14 at 04:07

The call will automatically translate to the internal IP – Bas Peeters Feb 26 '14 at 06:42
