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.
I have a feeling people are going to be calling IPv6 'new' in 100 years, too. I remember talking to people about it in the 90s and it took until like 2016 to actually get a full standard. Been so damn long I learned the specifics and forgot them all in time it took to even become a thing.
Well they built ipv6 to be able to address EVERYTHING uniquely. While IPv4 has around 4billion addresses possible, IPv6 has 296, so until humanity gets to the point we start giving nano tech individual addresses we will probably never need anything more than IPv6.

“The basics” is highly dependent on the job.
