EC2 InvalidElasticIP.NotFound error encountered when attempting to associate an Elastic IP with an EC2 instance.
The specified Elastic IP address does not exist or is incorrect.
Understanding Amazon EC2 and Elastic IPs
Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. One of the features of EC2 is the ability to associate Elastic IP addresses with instances, which are static IP addresses designed for dynamic cloud computing.
Identifying the Symptom
When working with EC2, you might encounter the error code InvalidElasticIP.NotFound. This error typically occurs when you attempt to associate an Elastic IP address with an EC2 instance, but the specified Elastic IP does not exist or is incorrect.
What You Observe
Upon executing a command to associate an Elastic IP with an instance, you receive an error message indicating that the Elastic IP address is not found. This prevents the successful association of the IP address with your instance.
Explaining the Issue
The InvalidElasticIP.NotFound error arises when the Elastic IP address specified in your command or API call does not match any existing Elastic IPs in your account or region. This could be due to a typo, an incorrect IP address, or the IP address having been released.
Common Causes
- The Elastic IP address was mistyped in the command or script.
- The Elastic IP address has been released and is no longer available.
- The Elastic IP address belongs to a different AWS account or region.
Steps to Resolve the Issue
To resolve the InvalidElasticIP.NotFound error, follow these steps:
Step 1: Verify the Elastic IP Address
Ensure that the Elastic IP address you are trying to associate is correct. Double-check the IP address for any typos or errors. You can list your Elastic IPs using the AWS Management Console or the AWS CLI:
aws ec2 describe-addresses
This command will list all Elastic IPs associated with your account in the current region.
Step 2: Check if the Elastic IP Has Been Released
If the Elastic IP address was previously released, it will no longer be available for association. You can check the release status in the AWS Management Console under the 'Elastic IPs' section.
Step 3: Ensure Correct Region and Account
Elastic IPs are region-specific and account-specific. Make sure you are operating in the correct AWS region and account where the Elastic IP was allocated.
Additional Resources
For more information on managing Elastic IPs, refer to the AWS Documentation on Elastic IPs. If you continue to experience issues, consider reaching out to AWS Support for further assistance.
