AWS::WAFv2::IPSet - Amazon CloudFormation
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).



This is the latest version of Amazon WAF , named Amazon WAFV2, released in November, 2019. For information, including how to migrate your Amazon WAF resources from the prior release, see the Amazon WAF developer guide.

Use an AWS::WAFv2::IPSet to identify web requests that originate from specific IP addresses or ranges of IP addresses. For example, if you're receiving a lot of requests from a ranges of IP addresses, you can configure Amazon WAF to block them using an IP set that lists those IP addresses.

You use an IP set by providing its Amazon Resource Name (ARN) to the rule statement IPSetReferenceStatement, when you add a rule to a rule group or web ACL.


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


{ "Type" : "AWS::WAFv2::IPSet", "Properties" : { "Addresses" : [ String, ... ], "Description" : String, "IPAddressVersion" : String, "Name" : String, "Scope" : String, "Tags" : [ Tag, ... ] } }


Type: AWS::WAFv2::IPSet Properties: Addresses: - String Description: String IPAddressVersion: String Name: String Scope: String Tags: - Tag



Contains an array of strings that specifies zero or more IP addresses or blocks of IP addresses that you want Amazon WAF to inspect for in incoming requests. All addresses must be specified using Classless Inter-Domain Routing (CIDR) notation. Amazon WAF supports all IPv4 and IPv6 CIDR ranges except for /0.

Example address strings:

  • For requests that originated from the IP address, specify

  • For requests that originated from IP addresses from to, specify

  • For requests that originated from the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128.

  • For requests that originated from IP addresses 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64.

For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.

Example JSON Addresses specifications:

  • Empty array: "Addresses": []

  • Array with one address: "Addresses": [""]

  • Array with three addresses: "Addresses": ["", "", ""]

  • INVALID specification: "Addresses": [""] INVALID

Required: Yes

A description of the IP set that helps with identification.

Required: No

Type: String

Pattern: ^[a-zA-Z0-9=:#@/\-,.][a-zA-Z0-9+=:#@/\-,.\s]+[a-zA-Z0-9+=:#@/\-,.]{1,256}$

Update requires: No interruption


The version of the IP addresses, either IPV4 or IPV6.

Required: Yes

Type: String

Allowed values: IPV4 | IPV6

Update requires: No interruption


The name of the IP set. You cannot change the name of an IPSet after you create it.

Required: No

Type: String

Pattern: ^[0-9A-Za-z_-]{1,128}$

Update requires: Replacement


Specifies whether this is for an Amazon CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an Amazon AppSync GraphQL API, an Amazon Cognito user pool, an Amazon App Runner service, or an Amazon Verified Access instance. Valid Values are CLOUDFRONT and REGIONAL.


For CLOUDFRONT, you must create your WAFv2 resources in the US East (N. Virginia) Region, us-east-1.

Required: Yes

Type: String


Update requires: Replacement


Key:value pairs associated with an Amazon resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each Amazon resource.


To modify tags on existing resources, use the Amazon WAF APIs or command line interface. With Amazon CloudFormation, you can only add tags to Amazon WAF resources during resource creation.

Required: No

Type: Array of Tag

Minimum: 1

Update requires: No interruption

Return values


The Ref for the resource, containing the resource name, physical ID, and scope, formatted as follows: name|id|scope.

For example: my-webacl-name|1234a1a-a1b1-12a1-abcd-a123b123456|REGIONAL.


The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.


The Amazon Resource Name (ARN) of the IP set.


The ID of the IP set.
