ForAllValues:IpAddressIfExists

compares a list of IP addresses in a request to a list of CIDR strings in your policy.

To match a request, the context key can be absent, but if it is present, all of the IP addresses in the request must match at least one of the CIDR strings in your policy.

You can NOT use policy variables in the value of this operator.

Warning

As far as we know, ForAllValues:IpAddressIfExists can never be used — no context keys exist that are an array of CIDR strings. It's documented here as an example of how it would work, but if you see it in the wild, it's probably a mistake.
