It's a fair question though, I would have thought the question is not 
meant to garner a specific number as an answer, it's meant to test the 
candidates understanding of the layers in a networking stack. If they 
answer with a precise number it would indicate that they do not 
understand that the hardware interface places no inherent limit on the 
number of IP addresses, Ethernet itself is all ARPs and MACs, Internet 
Protocol is handled further up the stack so the correct answer would be 
that it varies depending on what OS and which drivers/kernel you are 
running.

Or would I flunk the interview too?

Anyway, I think it's fair to ask questions that make the applicant 
reason the answer rather than simply knowing it, it probes their 
knowledge and talent far more succinctly and time is money. Not to say 
the ability to learn facts by rote isn't useful too but I'd contend less 
important than ability to learn and adapt.
