Those addresses can change arbitrarily often. Depending on what it is that you are actually trying to achieve with measures like this, you could do something that doesn't involve shoehorning an infrastructure detail into a security policy.

You might be able to simply ask DNS for the current IP addresses. If done regularly, you basically give control over your security perimeter to anyone in a position to influence nameserver responses, which might or might not be something you want.

Hopefully, it sold more on consoles. Otherwise, numbers like this could kill a fledgling studio outright.

Poor child. Imagine that happening to you every two hours.

Nun ja, bei TSMC gibt's 28nm jetzt seit zwölf Jahren.

Das kann aber für Leistungselektronik dennoch mehr als okay sein. Wenn Hauptabnehmer wirklich die Automobilbranche werden soll, wäre ein neuerer Prozess unter Umständen nicht besser (nur teurer).

edit — Kosten pro 100 Mgates, je nach Strukturbreite:

heise sagt: 28nm.

You could always try NixOS.

Arch may not be particularly easy to use, but it's a simple system, in that you can build a mental model of your entire setup with a fraction of the effort and time that you'd need to expend with other systems. It gives you the standard Linux experience without fuss, or handholding.

Nix, however, gives you several capabilities that other systems won't, but you're paying for that through its learning curve.
