EC2, Elastic IP Address, Elastic IP, Pricing, Cost, Monitoring

Elastic IP addresses stand out as a crucial component for resilient cloud computing in AWS Environments. Essential in the AWS Elastic Compute Cloud (EC2), they offer the flexibility to manage network interfaces with ease. Primarily, they are used for dynamic computing, allowing for more manageable server migration, fault tolerance, and the seamless redirection of traffic between different EC2 instances.

As AWS plans to introduce charges for all Elastic IP addresses from February 1, 2024, understanding their functionality and pricing becomes increasingly important. This article provides an overview of Elastic IP addresses, how they work, pricing models, and strategies for effective cost monitoring.

What is Elastic IP Address in EC2?

An Elastic IP address in AWS EC2 is a static IPv4 address crafted for the adaptable environment of cloud computing. This IP address is unique to your AWS account and remains under your control until you choose to release it.

One of its primary functions is to provide a consistent public IP address for your EC2 instances, ensuring your applications remain accessible even during instance failures or replacements.

Capabilities of Elastic IP Addresses

Elastic IP addresses in EC2 play a pivotal role in masking instance or software failures. This is achieved by quickly remapping the address to another instance within your account, ensuring minimal disruption and maintaining service continuity.

These addresses can be linked to DNS records, allowing your domain to point directly to your instance, which is particularly useful for hosting websites or running domain-based services.

Since Elastic IP addresses are public IPv4 addresses, they enable instances without their own public IPv4 to communicate with the internet. This capability is essential for tasks such as SSH or RDP access from your local machine to the instance. Their static nature makes them indispensable for maintaining a consistent point of contact for internet-facing applications like web servers, email servers, or VPNs.

  • Static Nature: Maintains a consistent public IP address for instances, crucial for services requiring a stable connection.
  • Failure Masking: Quickly remap the address to another instance within the account, offering resilience during instance or software failures.
  • DNS Integration: Can be linked to DNS records, enabling domains to directly point to instances, useful for web hosting.
  • Internet Communication: Enables instances without public IPv4 addresses to interact with the internet, facilitating remote access.
  • Operational Flexibility: Easily associate or reassociate with different EC2 instances for seamless failover and load balancing.
  • Control and Security: Retain control over the IP address even when not associated with any instance, allowing for strategic reallocation and security management.

Elastic IP addresses thus offer a blend of stability, flexibility, and control, crucial for managing public IP addresses in the ecosystem of AWS EC2.

EC2 Elastic IP Address Pricing

Pricing Structure

Starting February 1, 2024, all Elastic IP addresses, even those attached to running instances, will incur charges. This change signifies the importance of Elastic IP management to avoid unnecessary costs. To ensure cost-effectiveness, AWS users should regularly review and optimize their use of Elastic IP addresses, detaching or releasing any IPs that are not in active use

Upcoming Pricing Changes

Here are the new pricing rules that will go in effect from February 1st, 2024.

  1. Associated with Running Instances: The first Elastic IP address associated with a running instance is free. Additional Elastic IP addresses associated with the same running instance will incur a charge.
  2. Not Associated with Running Instances: Elastic IP addresses not attached to a running instance or linked to a stopped instance/unattached network interface will be charged.
  3. Elastic IP Remapping Charges: The first 100 remaps per month are free. Additional remaps over 100 per month are charged.
  4. Bring Your Own IP Addresses: No charge for Elastic IP addresses created from IP address prefixes brought into AWS.

How to View EC2 Elastic IP Addresses Cost

Monitoring and managing the costs of Elastic IP addresses in Amazon EC2 can be effectively done through AWS Cost Explorer. By following these straightforward steps, you can easily identify and analyze the specific costs associated with your Elastic IP addresses:

  • Navigating to Cost Explorer:
    • Begin by logging into the AWS Management Console.
    • Open AWS Cost Explorer from the console.
  • Choosing Costs:
    • In the Cost Explorer’s navigation pane on the left, select the “Costs” option.
  • Locating Elastic IP Costs:
    • In the “Costs by Service” section, look for “Amazon Elastic Compute Cloud – Elastic IP”.
    • You might need to scroll through the list or use the search bar for quicker access.

Analyzing Elastic IP Costs

Detailed Breakdown: The Cost Explorer will provide a detailed breakdown of costs, including trends over time, which can be valuable for understanding usage patterns.
Customization: You can customize the view in Cost Explorer to analyze data for specific time periods, or to compare costs between different services or resources.
Optimization Insights: By regularly reviewing these costs, you can identify opportunities for cost optimization, such as releasing unused Elastic IPs or associating them with running instances to avoid charges.


With the introduction of new pricing from February 1, 2024, AWS users must be cognizant of these changes and manage their resources strategically. It’s essential to leverage tools such as AWS Cost Explorer for regular monitoring, for a cost-effective approach to using Elastic IPs while still reaping their significant benefits. This balance of awareness and adaptation is key to optimizing cloud expenditure in their AWS environment.
