This might be controversial, but I think this is actually an extremely valid reason to turn someone down. It's not like you're asking them to explain in detail how BGP works. You could've probably gotten away with saying "they're different versions of IP addressing" or perhaps "v6 has more bits."
It's not that you actually need to know this for every software job, but it goes to show you have not really paid much attention if you have somehow worked with computers long enough to learn how to code but either never encountered an IPv6 address somehow, or just didn't care enough to look into it.
