To configure WAF to allow, block, or count requests that originated from IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24. To configure WAF to allow, block, or count requests that originated from the IP address 192.0.2.44, specify 192.0.2.44/32. WAF supports all IPv4 and IPv6 CIDR ranges except for /0.
All addresses must be specified using Classless Inter-Domain Routing (CIDR) notation. See also: AWS API Documentation Synopsis ¶Ĭontains an array of strings that specifies zero or more IP addresses or blocks of IP addresses. Generally, any inconsistencies of this type last only a few seconds. This temporary inconsistency can occur when you first associate a web ACL with an Amazon Web Services resource and when you change a web ACL that is already associated with a resource. Or if you add an IP address to an IP set used in a blocking rule, the new address might briefly be blocked in one area while still allowed in another. So, for example, if you change a rule action setting, the action might be the old action in one area and the new action in another area. Your changes are applied within seconds, but there might be a brief period of inconsistency when the changes have arrived in some places and not in others. When you make changes to web ACLs or web ACL components, like rules and rule groups, WAF propagates the changes everywhere that the web ACL and its components are stored and used. Provide the complete IP set specification to this call This operation completely replaces the mutable specifications that you already have for the IP set with the ones that you provide to this call.
