-- | A rule statement used to detect web requests coming from particular IP
-- addresses or address ranges. To use this, create an IPSet that specifies
-- the addresses you want to detect, then use the ARN of that set in this
-- statement. To create an IP set, see CreateIPSet.
--
-- Each IP set rule statement references an IP set. You create and maintain
-- the set independent of your rules. This allows you to use the single set
-- in multiple rules. When you update the referenced set, WAF automatically
-- updates all rules that reference it.
