Determine if the number of EC2-VPC Elastic IPs (EIPs) allocated per region is close to the limit number established by AWS for accounts that support Virtual Private Clouds (VPCs) and request limit increase in order to avoid encountering IP resource limitations on future EC2 provisioning sessions. As the IPv4 public IP addresses are a scarce resource nowadays, all AWS accounts are limited to 5 (five) Elastic IP addresses per region.
Monitoring your Elastic IP (EIP) limits will help you avoid public IP resources starvation in case you need to expand fast your AWS EC2-VPC infrastructure.
When you create your account, AWS sets automatically a fixed limit of 5 for the number of Elastic IPs available per region. To determine if your account has reached the EIP limit, perform the following:
To request an increase for the EC2-VPC Elastic IP limit, you need to perform the following:Note: Requesting to increase the limit for the number of Elastic IPs per region using the AWS API via Command Line Interface (CLI) is not currently supported.
