UpdateIPSet

Updates the specified IPSet.

Note

This operation completely replaces the mutable specifications that you already have for the IP set with the ones that you provide to this call.

To modify an IP set, do the following:

Retrieve it by calling GetIPSet
Update its settings as needed
Provide the complete IP set specification to this call

Temporary inconsistencies during updates

When you create or change a web ACL or other AWS WAF resources, the changes take a small amount of time to propagate to all areas where the resources are stored. The propagation time can be from a few seconds to a number of minutes.

The following are examples of the temporary inconsistencies that you might notice during change propagation:

After you create a web ACL, if you try to associate it with a resource, you might get an exception indicating that the web ACL is unavailable.
After you add a rule group to a web ACL, the new rule group rules might be in effect in one area where the web ACL is used and not in another.
After you change a rule action setting, you might see the old action in some places and the new action in others.
After you add an IP address to an IP set that is in use in a blocking rule, the new address might be blocked in one area while still allowed in another.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Addresses

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

Example address strings:

For requests that originated from the IP address 192.0.2.44, specify 192.0.2.44/32.
For requests that originated from IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24.
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": ["192.0.2.44/32"]
Array with three addresses: "Addresses": ["192.0.2.44/32", "192.0.2.0/24", "192.0.0.0/16"]
INVALID specification: "Addresses": [""] INVALID

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 50.

Pattern: .*\S.*

Required: Yes

Description

A description of the IP set that helps with identification.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: ^[\w+=:#@/\-,\.][\w+=:#@/\-,\.\s]+[\w+=:#@/\-,\.]$

Required: No

Id

A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 36.

Pattern: ^[0-9a-f]{8}-(?:[0-9a-f]{4}-){3}[0-9a-f]{12}$

Required: Yes

LockToken

A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException. If this happens, perform another get, and use the new token returned by that operation.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 36.

Pattern: ^[0-9a-f]{8}-(?:[0-9a-f]{4}-){3}[0-9a-f]{12}$

Required: Yes

Name

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

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: ^[\w\-]+$

Required: Yes

Scope

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 AWS AppSync GraphQL API, an Amazon Cognito user pool, an AWS App Runner service, or an AWS Verified Access instance.

To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1.
API and SDKs - For all calls, use the Region endpoint us-east-1.

Type: String

Valid Values: CLOUDFRONT | REGIONAL

Required: Yes

Response Syntax


{
   "NextLockToken": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

NextLockToken

A token used for optimistic locking. AWS WAF returns this token to your update requests. You use NextLockToken in the same manner as you use LockToken.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 36.

Pattern: ^[0-9a-f]{8}-(?:[0-9a-f]{4}-){3}[0-9a-f]{12}$

Errors

For information about the errors that are common to all actions, see Common Errors.

WAFDuplicateItemException

AWS WAF couldn’t perform the operation because the resource that you tried to save is a duplicate of an existing one.

HTTP Status Code: 400

WAFInternalErrorException

Your request is valid, but AWS WAF couldn’t perform the operation because of a system problem. Retry your request.

HTTP Status Code: 500

WAFInvalidOperationException

The operation isn't valid.

HTTP Status Code: 400

WAFInvalidParameterException

The operation failed because AWS WAF didn't recognize a parameter in the request. For example:

You specified a parameter name or value that isn't valid.
Your nested statement isn't valid. You might have tried to nest a statement that can’t be nested.
You tried to update a WebACL with a DefaultAction that isn't among the types available at DefaultAction.
Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL can't be associated.

HTTP Status Code: 400

WAFLimitsExceededException

AWS WAF couldn’t perform the operation because you exceeded your resource limit. For example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see AWS WAF quotas in the AWS WAF Developer Guide.

HTTP Status Code: 400

WAFNonexistentItemException

AWS WAF couldn’t perform the operation because your resource doesn't exist. If you've just created a resource that you're using in this operation, you might just need to wait a few minutes. It can take from a few seconds to a number of minutes for changes to propagate.

HTTP Status Code: 400

WAFOptimisticLockException

AWS WAF couldn’t save your changes because you tried to update or delete a resource that has changed since you last retrieved it. Get the resource again, make any changes you need to make to the new copy, and retry your operation.

HTTP Status Code: 400
