So, I'm going thru the 2nd course from a different instructor. I started to skip over the basics because I felt I already had it down pat. But I decided to go through it again. Now, I'll admit it was very boring going back over things that you already know. However, the first time around my head was spinning even when covering the basics. That "basics" aren't so simple when you don't know 'em.
Anyway, this time my head wasn't spinning and I was able to pick up some things that I didn't the first time around. Specifically, I was able to key in on public IP addresses and give it my undivided attention. The CCNA test is gonna cover all the basics and you gotta know 'em inside and out.
By the way, IP addressing and subnetting are a huge part of networking. That's where it all starts.
