Container for the parameters to the UpdateIPSet operation. Inserts or deletes IPSetDescriptor objects in an IPSet. For each IPSetDescriptor object, you specify the following values:

AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. 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:

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.

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