It doesn't, as it is run through an Oblivious HTTP relay run by a third party before getting to Apple's servers. So it has no IP information, and the requests use anonymous access tokens.
It is probably possible for an entity to break it, but it would require live access to both Apple and the third party (Likely Cloudflare) servers. And that is assuming there is only one third party routing OHTTP requests, otherwise you would need to monitor all of them, in real time, since the requests are transient.
