Create additional scopes

Follow the steps in this section to create an additional scope.

A scope is the highest-level container within IPAM. When you create an IPAM, IPAM creates two default scopes for you. Each scope represents the IP space for a single network. The private scope is intended for all private space. The public scope is intended for all public space. Scopes enable you to reuse IP addresses across multiple unconnected networks without causing IP address overlap or conflict.

When you create an IPAM, default scopes (one private and one public) are created for you. You can create additional private scopes. You cannot create additional public scopes.

You can create additional private scopes if you require support for multiple disconnected private networks. Additional private scopes allow you to create pools and manage resources that use the same IP space.

Important

If IPAM discovers resources with private IPv4 CIDRs, the resource CIDRs are imported into the default private scope and do not appear in any additional private scopes you create. You can move CIDRs from the default private scope to another private scope. For information, see Move VPC CIDRs between scopes.
