it's hard for me to explain what a "feeling of confidence" is -- part of the reason writing zines is so difficult is that it's hard to figure out *why* I feel confident about DNS or CSS or HTTP or Git. It's not because I know everything about it.
I think part of it is identifying a small subset of the Big Thing that I can use to get things done and that I feel confident with. I don't use every DNS feature, but I generally feel confident that I can deal with any DNS issue I run into.
