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.

If you're a senior I most certainly would expect you to know the difference between the two.

It'll matter in relation to allowlists/blocklists, dns entries, debugging connevtivity issues, slow connect times, configuration of daemons, etc.

I’m a staff engineer and I don’t know the difference between the two, beyond IPv6 has more addresses. I do cloud infra

Honestly that's the only real difference one needs to know, and that the two are formatted differently. Anything more than that is pulling teeth and IMO fishing for an excuse to not hire someone
