It. Never. Sticks!
Subnets? ...yeah - I know they exist (and ... 'matter'?)
IP classification ranges? Same
IPv4 vs IPv6? Holy freaking crap! Those make ABSOLUTELY no sense to me!
I care about only 2 or 3 things:
- what [private] IP range(s) do we have on this network?
- what NAT rule(s) do I need to know to get from 'here' to 'there' (and back again)?
- is my publicly-facing device group accessible from the 'public' internet?
Nothing. Else. Matters.
(yeah, yeah, yeah ... all those CCxx network engineers are having heart palpitations right now - but I. Do. Not. Care!)
