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.
If anyone you know claims to have expertise in the computer field and doesn’t know everything about DNS (there’s not much to know) then those people are clueless and by no means are they experts.
But there is. Between DNSSEC and EDNS you need to stay on top of stuff or your assumptions may be wrong. many supposed facts about DNS were assumptions by textbook authors that were invalidated years later, and that’s with the stuff that complies with the standards.
DNS from the 20th century was simple modern DNS really isn’t.
