How do I assign a custom primary private IP address to my Amazon Elastic Compute Cloud (Amazon EC2) instance?
Short description
You can associate a custom IP address to your Amazon EC2 instance while you configure the instance prior to launch. However, the IP address must be:
- A valid IPv4 address.
- In the CIDR range of the chosen subnet.
- Available. The IP address must not be tied to any other resource
Note: It's not possible to assign a new custom primary private IP address to an existing instance.
Resolution
- Configure an Amazon EC2 instance. For detailed steps, see Launching an instance using the launch instance wizard.
- In the Configure Instance Details section, for Network, select a virtual private cloud (VPC), or create a new VPC. For Subnet, select the subnet, or create a new subnet where you want to launch your instance.
- In the Network interfaces section, for Primary IP, enter the custom private IPv4 address.
- Complete the launch instance wizard configurations, and then launch the instance.
