--
-- 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 /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 <https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing 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.
--
-- For more information about how to use the AWS WAF API to allow or block HTTP requests, see the <http://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide> .
