when the level 2 intern researcher beside you spills the SCP-447-2 you’re researching on the floor and the Site Director walks in and slips and hits their head on a table and dies and the Site blows up because 447 contacted a dead body and the O5 council has to come log the cleanup operation and you get blamed for all of it and demoted to D-class
If you’ve ever had to fiddle with the DNS records for a website you own, you might have noticed that all of the records seem to contain the word “IN”, e.g.,:
example.com IN A 127.0.0.1
Depending on what tools you use to set them up, you might even know that “IN” is the record’s class - but in all likelihood you’ve never seen a record with any class other than “IN”, and your system probably doesn’t even give you the option to change it.
So what the heck is it doing there?
The answer, of course, is entirely mundane: it’s a remnant of the early days of the Internet, a sort of DNS namespacing mechanism that was never fully implemented outside of a handful of specialised applications, now retained mostly for legacy reasons.
The interesting part is the names of the other classes. It’s fairly obvious that “IN” stands for “Internet”, but can you guess what the other two classes are?
(I swear I’m not making this up.)
They’re Chaos (!) and Hesiod (!!).
Even that has a mundane explanation, mind - those just happen to be the names of the only two popular non-Internet applications that ever took advantage of classful DNS records.
Chaos and Hesiod.
Like, I’m not the only one who thought “what is this SCP Foundation horseshit?” when I first read those, right?
