god i'm old...
Edit: but it's great that some are teaching the basics that us seniors (!?) take for granted. It's why I particularly appreciated Julia Evans' DNS tutorials, which were explicitly written with that goal in mind; to educate the younger generation
This is covered by CS stuff like “what is the World Wide Web” and “who was Dennis Ritchie and why was he important”? Things of that nature in school. Do people who write code not know about IANA? The gatekeepers of all things Internet? Whose vaults contain the secrets to all of the internets protocols?
What’s really funny is all the extra field crap packed on the end like vp_token and such because a json blob would be too much.
I expect that if I'd walked around my last place of employment, asking software developers if they knew what IANA was, probably a single-digit percentage would have known (at best, small double digits). That's not a dig at them; I think you have an unrealistic expectation of what people should and do know about stuff these days.
Also, the existence of the IANA registry itself may be news to some.
