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:

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 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.
