IpamPrefixListResolverRuleRequest

Describes a CIDR selection rule to include in a request. This is used when creating or modifying resolver rules.

CIDR selection rules define the business logic for selecting CIDRs from IPAM. If a CIDR matches any of the rules, it will be included. If a rule has multiple conditions, the CIDR has to match every condition of that rule. You can create a prefix list resolver without any CIDR selection rules, but it will generate empty versions (containing no CIDRs) until you add rules.

There are three rule types. Only 2 of the 3 rule types support conditions - IPAM pool CIDR and Scope resource CIDR. Static CIDR rules cannot have conditions.

Static CIDR: A fixed list of CIDRs that do not change (like a manual list replicated across Regions)
IPAM pool CIDR: CIDRs from specific IPAM pools (like all CIDRs from your IPAM production pool)

If you choose this option, choose the following:
- IPAM scope: Select the IPAM scope to search for resources
- Conditions:
  - Property
    
    IPAM pool ID: Select an IPAM pool that contains the resources
    
    CIDR (like 10.24.34.0/23)
  - Operation: Equals/Not equals
  - Value: The value on which to match the condition
Scope resource CIDR: CIDRs from AWS resources like VPCs, subnets, EIPs within an IPAM scope

If you choose this option, choose the following:
- IPAM scope: Select the IPAM scope to search for resources
- Resource type: Select a resource, like a VPC or subnet.
- Conditions:
  - Property:
    
    Resource ID: The unique ID of a resource (like vpc-1234567890abcdef0)
    
    Resource owner (like 111122223333)
    
    Resource region (like us-east-1)
    
    Resource tag (like key: name, value: dev-vpc-1)
    
    CIDR (like 10.24.34.0/23)
  - Operation: Equals/Not equals
  - Value: The value on which to match the condition

RuleType

The type of CIDR selection rule. Valid values include include for selecting CIDRs that match the conditions, and exclude for excluding CIDRs that match the conditions.

Type: String

Valid Values: static-cidr | ipam-resource-cidr | ipam-pool-cidr

Required: Yes

Conditions

The conditions that determine which CIDRs are selected by this rule. Conditions specify criteria such as resource type, tags, account IDs, and Regions.

Type: Array of IpamPrefixListResolverRuleConditionRequest objects

Required: No

IpamScopeId

The ID of the IPAM scope from which to select CIDRs. This determines whether to select from public or private IP address space.

Type: String

Required: No

ResourceType

For rules of type ipam-resource-cidr, this is the resource type.

Type: String

Required: No

StaticCidr

A fixed list of CIDRs that do not change (like a manual list replicated across Regions).

Type: String

Required: No
