Note

Amazon WAF Classic support will end on September 30, 2025.

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

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

Creates an IPSet, which you use to specify which web requests that you want to allow or block based on the IP addresses that the requests originate from. For example, if you're receiving a lot of requests from one or more individual IP addresses or one or more ranges of IP addresses and you want to block the requests, you can create an IPSet that contains those IP addresses and then configure Amazon WAF to block the requests.

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

Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateIPSet request.
Submit a CreateIPSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
Submit an UpdateIPSet request to specify the IP addresses that you want Amazon WAF to watch for.

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