IpamPrefixListResolverRuleCondition

Describes a condition within a CIDR selection rule. Conditions define the criteria for selecting CIDRs from IPAM's database based on resource attributes.

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

cidr

A CIDR block to match against. This condition selects CIDRs that fall within or match the specified CIDR range.
