Jumping from "they don't host gnome.org" to "GNOME doesn't use any of their infrastructure for any purpose" seems like a leap?
Fosshost provides (provided) resources to those projects, but does not have any IP ownership.
Redhat does not own (100%) of GNOME IP, there are many contributors. Also redhat is just a brand asset of IBM, so it cannot actually own anything.
Parent means IP as in Internet Protocol, not Intellectual property. The DNS for gnome.org resolves to 8.43.85.5, which lists Red Hat Inc. as the ISP. Indicating it's unlikely to be hosted by Fosshost.
Oh I see what you mean. Fosshost is unique in that they have a lot of arm64 metal floating around (maybe locked up in a DC soon?). They typically have offered it up for CI or distro build servers.
I said gnome.org's IP, not GNOME's. As the sibling comment stated; I am lazily referring to the site's IP address.
