When you create an IPAM, a private and public default scope are created for you. If you want to create additional scopes, they will be private scopes. You cannot create additional public scopes. | \* *Resource-locale pair:* When setting allocation rules, you must specify both a resource type (the AWS resource like EIPs, ALBs, or RDS clusters) and a locale (the AWS Region or Local Zone where the rule applies). Allocation rules are scoped to this resource type and locale combination. For example, if you're setting a policy for EIPs in us-east-1, you can set up to 10 rules for that specific resource-locale pair\*.
