Yeah, that. But how do you get those folks through the HR
He'll have to come up with another weedout question, like what's a /27?
I'm constantly amazed/disappointed when we interview candidates for a
senior Linux admin job and they just don't know modern networking at all.
Even better question, with multiple right answers, how many IPs are in a
/32?
I would use questions such as the following:
1. How many end-sites can be numbered from a single /32.
(Correct answers: IPv4 - 1, IPv6 - 65,536)

instead of MD5 authentication?

AIX actually supported PMTUD for UDP. Not sure if it still does. Yes, it was
