Use IPAM with a single account
If you choose not to Integrate IPAM with accounts in an Amazon Organization, you can use IPAM with a single Amazon account.
When you create an IPAM in the next section, a service-linked role is automatically created for the Amazon VPC IPAM service in Amazon Identity and Access Management. IPAM uses the service-linked role to monitor and store metrics for CIDRs associated with EC2 networking resources. For more information on the service-linked role and how IPAM uses it, see Service-linked roles for IPAM.
Important
If you use IPAM with a single Amazon account, you must ensure that the Amazon account
you use to create the IPAM uses a IAM role with a policy attached to it that permits the
iam:CreateServiceLinkedRole action. When you create the IPAM, you
automatically create the AWSServiceRoleForIPAM service-linked role. For more information
on managing IAM policies, see Editing IAM policies in
the IAM User Guide.
Once the single Amazon account has permission to create the IPAM service-linked role, go to Create an IPAM.
