UpdateIPSetCommand

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic  in the developer guide.

For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes IPSetDescriptor objects in an IPSet. For each IPSetDescriptor object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor object, you delete the existing object and add a new one.

  • The IP address version, IPv4 or IPv6.

  • The IP address in CIDR notation, for example, 192.0.2.0/24 (for the range of IP addresses from 192.0.2.0 to 192.0.2.255) or 192.0.2.44/32 (for the individual IP address 192.0.2.44).

AWS WAF supports IPv4 address ranges: /8 and any range between /16 through /32. AWS WAF supports IPv6 address ranges: /24, /32, /48, /56, /64, and /128. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .

IPv6 addresses can be represented using any of the following formats:

  • 1111:0000:0000:0000:0000:0000:0000:0111/128

  • 1111:0:0:0:0:0:0:0111/128

  • 1111::0111/128

  • 1111::111/128

You use an IPSet to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet that specifies those IP addresses, and then configure AWS WAF to block the requests.

To create and configure an IPSet, perform the following steps:

  1. Submit a CreateIPSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.

When you update an IPSet, you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.

You can insert a maximum of 1000 addresses in a single request.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { WAFClient, UpdateIPSetCommand } from "@aws-sdk/client-waf"; // ES Modules import
// const { WAFClient, UpdateIPSetCommand } = require("@aws-sdk/client-waf"); // CommonJS import
const client = new WAFClient(config);
const input = { // UpdateIPSetRequest
  IPSetId: "STRING_VALUE", // required
  ChangeToken: "STRING_VALUE", // required
  Updates: [ // IPSetUpdates // required
    { // IPSetUpdate
      Action: "INSERT" || "DELETE", // required
      IPSetDescriptor: { // IPSetDescriptor
        Type: "IPV4" || "IPV6", // required
        Value: "STRING_VALUE", // required
      },
    },
  ],
};
const command = new UpdateIPSetCommand(input);
const response = await client.send(command);
// { // UpdateIPSetResponse
//   ChangeToken: "STRING_VALUE",
// };

Throws

Name
Fault
Details
WAFInternalErrorException
server

The operation failed because of a system problem, even though the request was valid. Retry your request.

WAFInvalidAccountException
client

The operation failed because you tried to create, update, or delete an object by using an invalid account identifier.

WAFInvalidOperationException
client

The operation failed because there was nothing to do. For example:

  • You tried to remove a Rule from a WebACL, but the Rule isn't in the specified WebACL.

  • You tried to remove an IP address from an IPSet, but the IP address isn't in the specified IPSet.

  • You tried to remove a ByteMatchTuple from a ByteMatchSet, but the ByteMatchTuple isn't in the specified WebACL.

  • You tried to add a Rule to a WebACL, but the Rule already exists in the specified WebACL.

  • You tried to add a ByteMatchTuple to a ByteMatchSet, but the ByteMatchTuple already exists in the specified WebACL.

WAFInvalidParameterException
client

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

  • You specified an invalid parameter name.

  • You specified an invalid value.

  • You tried to update an object (ByteMatchSet, IPSet, Rule, or WebACL) using an action other than INSERT or DELETE.

  • You tried to create a WebACL with a DefaultAction Type other than ALLOW, BLOCK, or COUNT.

  • You tried to create a RateBasedRule with a RateKey value other than IP.

  • You tried to update a WebACL with a WafAction Type other than ALLOW, BLOCK, or COUNT.

  • You tried to update a ByteMatchSet with a FieldToMatch Type other than HEADER, METHOD, QUERY_STRING, URI, or BODY.

  • You tried to update a ByteMatchSet with a Field of HEADER but no value for Data.

  • Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.

WAFLimitsExceededException
client

The operation exceeds a resource limit, for example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see Limits  in the AWS WAF Developer Guide.

WAFNonexistentContainerException
client

The operation failed because you tried to add an object to or delete an object from another object that doesn't exist. For example:

  • You tried to add a Rule to or delete a Rule from a WebACL that doesn't exist.

  • You tried to add a ByteMatchSet to or delete a ByteMatchSet from a Rule that doesn't exist.

  • You tried to add an IP address to or delete an IP address from an IPSet that doesn't exist.

  • You tried to add a ByteMatchTuple to or delete a ByteMatchTuple from a ByteMatchSet that doesn't exist.

WAFNonexistentItemException
client

The operation failed because the referenced object doesn't exist.

WAFReferencedItemException
client

The operation failed because you tried to delete an object that is still in use. For example:

  • You tried to delete a ByteMatchSet that is still referenced by a Rule.

  • You tried to delete a Rule that is still referenced by a WebACL.

WAFStaleDataException
client

The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.

WAFServiceException
