HNOPS02-BP01 Use IP address management tool
Use IP Address Manager tool to automate workflows to efficiently manage IP addresses. It helps to organize and monitor the IP address space and automatically allocate CIDRs using specific business rules.
Desired outcome:
-
Organized and efficiently managed IP addressing scheme across hybrid environments
-
Get clear visibility, prevents overlapping addresses, and supports scalable network growth.
Level of risk exposed if this best practice is not established: High
Benefits of establishing this best practice:
-
Efficient route summarization, allowing organizations to advertise larger CIDR blocks instead of individual prefixes.
-
Clean network boundaries and facilitate easier security management.
-
Achieve better resource utilization through automated IP address assignment, eliminating manual tracking processes and reducing human errors.
Implementation guidance
-
Create a hierarchical structure of IP pools that align with your organizational needs and geographical presence. For example, you can use services such as Amazon VPC IPAM.
-
Establish clear policies for CIDR allocation, including reserved ranges for specific purposes such as Amazon VPCs, subnets, and on-premises networks.
-
Implement workflows for IP address assignment, such as using Amazon VPC IPAM allocation rules.
