-- 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'.
-- -   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 more
-- information about CIDR notation, see the Wikipedia entry
-- <https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing Classless Inter-Domain Routing>.
--
-- 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
-- <http://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
