I’ve been using a lot of this stuff for decades, and the more I understand it, the better I feel. The less I understand it, well, I still work with it, but I treat it with superstition, like I’m dealing with fae folk, where there are rules, but I’m not allowed to know them, so I’d best throw salt everywhere and behind my back make the sign against strong enchantment.
I know that there are A records and AAAA records and CNAME and TXT records and so on, and that there are zones, and authority zone hierarchies. But bind and rndc themselves have always remained, for me, arcane mysteries (always increment that serial number!) and I don’t know what forwarding or recursive mean. Why run (or why not run) a DNS server on every PC?
