CLI tool that shows the future public IPv4 costs for a variety of AWS resources across all AWS regions from an account.

AWS IPv4 Costs Viewer

This tool shows the future public IPv4 costs for a variety of AWS resources (see below) across all AWS regions from an account in a user-friendly terminal UI.

Background

As of February 2024, AWS starts charging 3.65 USD monthly for each public IPv4 address. We will get charged regardless if we provision the IP ourselves or if AWS services provision IPv4 IPs on our behalf, such as for Load balancers.

AWS also offers a similar dashboard in the AWS console, and such data is available also in the cost visibility dashboards, but we try to also provide costs and even utilization metrics for some resources, which allow AWS customers to take more informed optimization actions. And the fact that this is open-source software makes it easier to integrate into different tools.

Features

• Fetch and display the future IPv4 costs associated with:
  • EC2 Instances
  • Elastic IPs (EIPs)
  • Load Balancers (LBs)
  • Elastic Network Interfaces (ENIs)
• Interactive terminal UI to navigate through the data.
• Shows ELB metrics such as the amount of network traffic over the last 7 days, to inform optimization actions.
• IPv4 addresses for load balancers are determined through the DNS resolution of their public FQDN.
• Data is fetched in parallel across regions and services for faster results.
• Name tags are shown wherever possible, with failover to tags created automatically by ASGs and CloudFormation stacks.

Further improvement ideas (contributions welcome)

• Add support for more resources included in the ENI list. (e.g. ECS, APIGW, etc.), see here for more details.
• Add support for additional resources not included in the ENI list. (e.g. VPN endpoints, etc.)
• Properly integrate the subnets view currently available when running with --subnets.
• Add support to dump data as CSV, JSON, YAML, XLSX, and whatever other file types may make sense.
• Add some nice anonymized screenshots to the Readme file. (DONE)

Prerequisites

• Go (1.16 or later)
• AWS CLI credentials set in the shell environment, for a user/role configured with appropriate permissions.

Installation

go install github.com/leanercloud/aws-ipv4-cost-viewer@latest

Usage

After installation, you can run the tool with:

aws-ipv4-costs-viewer

Navigate through the UI using the arrow keys. Press ESC to exit.

Public IPs attached to 34 Elastic Network Intefaces: $124.10
EC2: $25.55 for 7 instances
Load balancers: $83.95 for 23 load balancer IPs
and $18.25 for 3 Elastic IPs
Note: ENI costs also include those for EC2, LB and EIP. Still, unattached EIPs have an additional cost, so the total IPv4 cost isn't exactly the same as the ENI cost
