IpAddressIfExists

IpAddressIfExists

IpAddressIfExists compares an IP address in a request to a list of CIDR strings in your policy.

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

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