Why is DNS still hard to learn?

I feel like DNS is one of the more straightforward protocols, especially on a practical level, and especially given that most interfaces are a dropdown and two text boxes.

I have noticed a lot of developers shy away from it, probably because they don't use it much or it's not their job (rather than it being hard).

"Dropdown and two text boxes" undersells it.

Here is the list of several dozen record types: https://www.iana.org/assignments/dns-parameters/dns-paramete...

Sure, but I'm talking about a day-to-day practical level. Most people will only ever need to modify A/CNAME, occasional MX and TXT, and maybe an SOA/PTR.

Even the more arcane record types (as far as I've ever used them) are essentially key-value pairs with the record type analogous to a namespace.

AAAA

Also NS is reasonably common.

Yeah, that's the dropdown.

Exactly. Why waste time learning something I will only use once or twice a year or 10 times in my career? Or that someone else (who is an expert) can fix for me?

I guarantee the problem space that dns solves is something you will run into in your career. Best to have some knowledge of systems like that so you can design them.

Of the similarly-aged protocols, I think it's the most difficult (which is not saying much).

SMTP and HTTP can be pretty easily done by hand, which makes them more accessible to a person learning the protocols themselves.

DNS the protocol is simple, but I do think there's something to be said for how complex it is if you want to say, set up your own domain from which to reliably send e-mail.
