@scottalanmiller I agree. I great book on networking basics. Still use that information today. 😉
Yeah, it is amazing how many times I have to be like "if only people knew the networking basics from that book, they'd know how to do this thing" even today. Back then, it was "no one knows networking, here is how it works." Everything in that book should be common knowledge today, almost. At least for every IT position, including intern. And yet, I feel fewer people know it than before!
Network Documentation is very very important, for Network Admins is a must, because for example a new team member joins, this information will be useful to acknowledge the network infrastructure.
