Wait until DNS comes up again. I don't know how many DevOps, SRE, Senior Architects, etc. that I've worked with that just don't understand how names are resolved. There's a wide array of specialists that don't understand general fundamentals.

I also see this. Getting an MX record or TLS cert deployed is often a source of confusion, even with "seniors.'

Personally, I understand the fundamentals until they all change and DNS has had a lot of outgrowths relating to encryption, Email spam prevention, IPv6, etc that have made things a lot muddier for me over time.
