i’ve personally met tech influencers w certifications that imply high level networking knowledge, who literally could not tell you what ARP is or how it works. could not describe the OSI model or the difference between routing & switching. & they’re gearing up to sell you things.

Them: It's too complicated to explain, if you knew networking, you'd understand that
Me: You must work in infosec...
if we were all building a house...
Neteng: We've secured it w/ biometric locks & reinforced doorframes
Infosec: The boathouse has no locks
Neteng: There is no boat. Not even a lake.
Most certification junkies can describe everything in high level. But the moment you do down to LLD level, they either find excuses or simple say it wrong. Only very few are honest and say 'had to double check but it's this and that".
Whether you’re red or blue, you gotta know how networks *work* first. Then you can break/defend them!
If it weren't for my home network I probably wouldn't deal with ARP at all any more, but that's part of why I keep playing with it.
