How do I assign a custom primary private IP address to my Amazon Elastic Compute Cloud (Amazon EC2) instance?
You can associate a custom IP address to your EC2 instance while the instance is being configured prior to launch. However, the IP address must be:
- A valid IPv4 address
- In the CIDR range of the chosen subnet
- Available—that is, it 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.
- Configure an EC2 instance. For detailed steps, see Launching an Instance Using the Launch Instance Wizard.
- In the Configure Instance Details section, for Network, select a 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, enter the custom private IPv4 address.
- Finish configuring and then launch the instance.
