Apple iCloud Private Relay IP Range Check
This rule checks if a given IP address falls within the known IP ranges used by Apple's iCloud Private Relay service. It retrieves a list of IPv4 and IPv6 ranges from a GitHub repository and then uses KQL's `ipv4_is_in_any_range` and `ipv6_is_in_any_range` functions to determine if the provided IP address is part of these ranges. This can be used to identify traffic potentially obfuscated by iCloud Private Relay.
