> know how to change their IP address

My first job was as a sys admin, and I was explicitly told that they hired me because my eyes didn't glaze over when the interview covered their static ip network

The thing is, that was then. Now suggesting a static ip immediately begs the question of what wouldn't you use dns to solve the problem instead.

Dns doesn't solve all cases but it does now cover a significant number. The industry has changed enough that I no longer expect anyone who doesn't have some background with networking specific concerns to know this stuff

I couldn't tell you if this is a net positive, but it definitely feels less relevant to my day-to-day than being competent with whatever DSL your CI pipeline uses
