# AWS::EC2::IPAMPrefixListResolverTarget
<a name="aws-resource-ec2-ipamprefixlistresolvertarget"></a>

An IPAM prefix list resolver target is an association between a specific customer-managed prefix list and an IPAM prefix list resolver. The target enables the resolver to synchronize CIDRs selected by its rules into the specified prefix list, which can then be referenced in AWS resources.

## Syntax
<a name="aws-resource-ec2-ipamprefixlistresolvertarget-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-resource-ec2-ipamprefixlistresolvertarget-syntax.json"></a>

## Return values
<a name="aws-resource-ec2-ipamprefixlistresolvertarget-return-values"></a>

### Ref
<a name="aws-resource-ec2-ipamprefixlistresolvertarget-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the prefix list resolver target ID. For example: `ipam-plrt-111122223333`.

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).
