All parked domains could lead to the same IP. A single web server could distinguish which domain itβs contacted for, using the HTTP headers for example, and serve different content (probably all 301-redirects, but to relevant other websites of Apple).
I suspect they are only parking those names after recovering them or buying them preemptively. Domain names are cheap, so why not. I don't think that's any argument for the possession of the /8 though.
I remember Google had ownership of duck.com until recently, so they probably participate in the wholesale acquisition of random domains as well [2].
