Why is DNS often joked about in the I.T. Industry? - eviltoast

I should clarify I wasn’t a upper level sys admin managing those servers, I just used them or maintained accounts being a rank and file technician

While I get the fundamental concept of DNS as a phonebook for your IPs. I am not sure why it is joked around if something goes haywire or someone breaks something.

Is it because if you get no DNS, people can’t log in through their AD accounts, browse the Internet?

Afaik DNS is a bit of a rabbit hole topic, maybe that’s why people joke about it due to DNS being this “No one really knows how this magic name matching box works”?

Please correct me, I’d genuinely like to know why this is prevalent from you guys.

    Like, when I install uBlock it comes with everything it needs. If I run Unbound does it block ads out of the box or do I need to point it to some list?

      Unbound is a high-level DNS server. It needs you to provide it hosts in a list or provide it with regex scripts (for dynamic and more efficient blocking). It can block ads at the DNS level just like PiHole (because that’s literally what PiHole and AdGuard use under the hood, but add their fancy GUIs)

      I would avoid it unless you know what you’re doing, and recommend reading the docs on their website and testing/breaking it within a Docker container.

      It’s the difference between buying a car from a dealership (PiHole, AdGuard, etc) or building your own from scratch (Unbound). One is very limited, whereas building it and running it yourself you get to do way more than what’s spoon fed to you.

        Ah okay. Unbound is arch, pi hole is Ubuntu. I have gripes with pi hole but it’s never not worked for me. I might just do that instead (if I ever get around to it lmao)
