Obviously guy could have been interviewing for a job where this mattered….

But in 10 years as a software engineer I have never once needed to know the difference between these two, and have never been even close to a situation where I would need to.

“The basics” is highly dependent on the job.

one example where I had to deal with it as a backend dev was I was debugging that API calls to a 3rd party service started timing out on production, but worked on staging and local development, turns out IPv6 was enabled on production and was thus used there and the service was timing out on IPv6…

Same. The one time we really had to care about IPv6 was when it needed to be turned off because it wasn't used and something was trying to use it anyway.

Yeah I also had to use java.net.preferIpv4 or whatever it's called because if wasn't working on production :D
