[LPI102] So if we're covering RFC 1918 in LPIC-1, but making no mention of the common /8, /16 and /24 CIDRs, I really don't understand? To me, this is absolutely foundational, and only takes an extra paragraph or 3-4 bullets max. That's like skipping the common IPv6 CIDRs when covering the LL and ULA . It makes no sense to me. I've seen texts do it, which means it's practically useless, and it prevents the junior sysadmin from knowing everything they should about an IP address when they run "ip addr." It's not that hard to understand, and why we leave that gap is beyond me, when they will run "ip addr" as a junior sysadmin. But that's just my biased opinion. -- bjs [LPI102] https://www.lpi.org/linux-certifications/programs/lpic-1/exam-102/
