Using Console

Sure. Here are the steps to remediate the EC2-VPC Elastic IP Address Limit Should Not Be Reached issue in AWS:

  1. Login to your AWS console.
  2. Navigate to the EC2 dashboard.
  3. Click on the “Elastic IPs” option from the left navigation pane.
  4. Check the “Current Limit” column to see the current limit of Elastic IP addresses for your account.
  5. If the current limit has been reached, you will need to request a limit increase. Click on the “Request limit increase” button.
  6. Fill out the form with the required details, such as your use case and the new limit you require.
  7. Submit the form and wait for AWS to review and approve your request.
  8. Once the limit has been increased, you can allocate new Elastic IP addresses as needed.

That’s it! By following these steps, you should be able to remediate the EC2-VPC Elastic IP Address Limit Should Not Be Reached issue in AWS.

​
Using CLI

To remediate the “EC2-VPC Elastic IP Address Limit Should Not Be Reached” misconfiguration in AWS using AWS CLI, follow these steps:

  1. Check the current limit for Elastic IP addresses in your VPC. Run the following command:
aws ec2 describe-account-attributes --attribute-names vpc-max-elastic-ips
  1. If the current limit is reached, you need to request a higher limit. To do this, run the following command:
aws ec2 modify-account-attribute --attribute-name vpc-max-elastic-ips --max-elastic-ips <new_limit>

Replace <new_limit> with the new limit you want to request.

  1. If the current limit is not reached, you can release any unused Elastic IP addresses to free up space. To do this, run the following command:
aws ec2 release-address --public-ip <public_ip_address>

Replace <public_ip_address> with the Elastic IP address you want to release.

  1. Repeat step 3 for any other unused Elastic IP addresses until you have freed up enough space to stay within the limit.

  2. Finally, you can create a CloudWatch alarm to monitor the usage of Elastic IP addresses in your VPC. This will alert you if you are approaching the limit again in the future. To create the alarm, follow these steps:

  • Open the CloudWatch console.
  • Click “Alarms” in the left navigation pane.
  • Click “Create alarm”.
  • Under “Select metric”, choose “EC2” and then “Per-Instance Metrics”.
  • Choose the “Elastic IP addresses allocated” metric.
  • Set the threshold for the alarm to the maximum number of Elastic IP addresses you want to allow.
  • Choose the action to take when the alarm is triggered (e.g. send an email notification).

By following these steps, you should be able to remediate the “EC2-VPC Elastic IP Address Limit Should Not Be Reached” misconfiguration in AWS using AWS CLI.

​
Using Python

To remediate the EC2-VPC Elastic IP Address Limit Should Not Be Reached misconfiguration for AWS using python, you can follow these steps:

  1. Check the current number of Elastic IP addresses in use in your AWS account by using the boto3 library in Python. You can use the describe_account_attributes method of the EC2 client to get this information. Here’s an example code snippet:
import boto3

ec2 = boto3.client('ec2')
response = ec2.describe_account_attributes(
    AttributeNames=['max-elastic-ips']
)
max_ips = response['AccountAttributes'][0]['AttributeValues'][0]['AttributeValue']
print("Max Elastic IPs allowed:", max_ips)

response = ec2.describe_addresses()
num_ips = len(response['Addresses'])
print("Number of Elastic IPs in use:", num_ips)
  1. If the number of Elastic IPs in use is approaching the limit, you can release some unused Elastic IPs to free up space. You can use the release_address method of the EC2 client to release an Elastic IP. Here’s an example code snippet:
import boto3

ec2 = boto3.client('ec2')
response = ec2.describe_addresses()
for address in response['Addresses']:
    if not address['AssociationId']:
        print("Releasing unused Elastic IP:", address['PublicIp'])
        ec2.release_address(AllocationId=address['AllocationId'])
  1. If you need more Elastic IPs than the current limit, you can request a limit increase from AWS support. You can use the create_case method of the AWS support client to create a support case. Here’s an example code snippet:
import boto3

support = boto3.client('support')
response = support.create_case(
    subject='Request for Elastic IP limit increase',
    serviceCode='amazon-ec2',
    severityCode='low',
    categoryCode='limit-increase',
    communicationBody='Please increase my Elastic IP limit to X.'
)
case_id = response['caseId']
print("Support case created with ID:", case_id)

Note: You will need to have the appropriate IAM permissions to perform these actions.
