1. Overview of Amazon VPC IP Address Manager

Amazon VPC IP Address Manager (IPAM) is a fully managed service that enables you to efficiently manage IP addresses within your VPC. It provides a unified and centralized platform for IP address planning, allocation, and tracking.

Key features of Amazon VPC IP Address Manager include:
– Centralized IP address management: IPAM consolidates the management of IP addresses across multiple VPCs, AWS accounts, and AWS Regions. This allows for better visibility and control over your IP address space.
– Simplified IP address allocation: IPAM simplifies the process of allocating IP addresses to resources within your VPC, such as EC2 instances or VPCs.
– Automatic IP address tracking: IPAM automatically tracks the usage of IP addresses and provides real-time insights into IP address utilization.
– Integration with other AWS services: IPAM seamlessly integrates with other AWS services, such as AWS Identity and Access Management (IAM) for secure access control, and AWS Organizations for multi-account management.

2. Introduction to the Free Tier

Amazon VPC IP Address Manager now offers a Free Tier, which allows users to access public IP address planning features within their AWS account and Region.

In the Free Tier, users can:
– Bring their own IP (BYOIP) addresses to AWS and use them with resources in their AWS account.
– Provision Amazon provided contiguous IPv6 blocks for use with resources such as EC2 instances or VPCs.
– Utilize Public IP Insights to gain a unified view of their public IPv4 addresses across AWS accounts and Regions.
– Identify and optimize inefficiently used or unused IPv4 addresses to reduce costs.

3. Public IP Address Planning with BYOIP Addresses

The Amazon VPC IP Address Manager Free Tier allows users to bring their own IP (BYOIP) addresses to AWS and utilize them within their VPC.

Key points to consider when planning your BYOIP address implementation:
– Ensure that your BYOIP addresses comply with AWS requirements and guidelines.
– Follow the necessary procedures to announce your BYOIP addresses to AWS.
– Implement border gateway protocol (BGP) routing to enable communication between your on-premises network and your BYOIP addresses in AWS.
– Utilize IPAM to track and manage the allocation of your BYOIP addresses within your VPC.

4. Provisioning Amazon Provided Contiguous IPv6 Blocks

With the Free Tier of Amazon VPC IP Address Manager, users can provision Amazon provided contiguous IPv6 blocks for use with their EC2 instances and VPCs.

Here are the steps to provision Amazon provided contiguous IPv6 blocks:
1. Access the IP Address Manager console in the AWS Management Console.
2. Select the desired AWS account and Region.
3. Navigate to the IPv6 Blocks section and choose “Provision”.
4. Specify the size of the IPv6 block and configure any additional settings.
5. Confirm the provisioning process and wait for the block to be allocated.
6. Utilize the allocated IPv6 block in your VPC for assigning addresses to resources.

5. Utilizing Public IP Insights for IPv4 Optimization

One of the key features added to the Free Tier of Amazon VPC IP Address Manager is Public IP Insights. This feature provides a unified view of your public IPv4 addresses across multiple AWS accounts and Regions, allowing you to optimize your public IPv4 address spend.

Here’s how you can utilize Public IP Insights for IPv4 optimization:
1. Access the IP Address Manager console and select the desired AWS account and Region.
2. Navigate to the Public IP Insights dashboard.
3. Review the list of allocated IPv4 addresses and identify any addresses that are not in use or inefficiently used.
4. Optimize your public IPv4 address spend by releasing unused addresses or reallocating them to more efficient resources.
5. Utilize IPAM’s tracking and reporting capabilities to monitor the impact of your optimizations and ensure ongoing efficiency.

6. Advanced Tier for Retrospective Audits and Cross-Account/Region Planning

While the Free Tier of Amazon VPC IP Address Manager provides basic IP address management features within your AWS account and Region, the Advanced Tier is designed for more advanced use cases.

Key features and use cases of the Advanced Tier include:
– Retrospective audits: With the Advanced Tier, you can perform retrospective audits of your IP address allocations and usage across multiple AWS accounts and Regions. This helps identify historical inefficiencies and optimize your IP address management strategies.
– Cross-account and cross-Region planning: Advanced Tier allows you to plan IP address assignments across multiple AWS accounts and Regions. This is beneficial for organizations with complex network configurations and resource deployments.
– Enhanced reporting and analytics: The Advanced Tier provides more advanced reporting and analytics capabilities, enabling you to gain deeper insights into IP address utilization and trends.
