Why is DNS still hard to learn?
It’s not. It’s one of the few things that hasn’t changed much and it’s operation is fairly straightforward.dig is a little confusing. It’s more capable but less straightforward than good old nslookup (which still works fine BTW).I think partly DNS and the core protocols may seem confusing to younger people in the industry because so much stuff “just works” now.For example, today wifi routers “just work” right out of the box. In the early 2000s it would have taken a network engineer with knowledge of DNS, IP, Ethernet, RFC1918, actual routing protocols and whole bunch of other stuff to set something like that up and they’d have well known how it worked and why it was configured the way it was.If you think DNS from a client can perspective is confusing, try configuring BIND ;-)/OldNeckBeardRant
