> Sure, if you run an air-gapped network in some military facility, you can get things working without DNS, but 99.999% networks can't work without a DNS.

It's funny you say that, because in the air-gapped network in some military facility I work in, we actually replicate certain public DNS entries to have some specific systems and services working for our developers.

Of course, you want SNMP monitors get you and email as an alert, you have to setup auth DNS with xyz.local and use it in air-gapped environments for your alert mails. Hard drive failure?, RX/TX errors on a switch port? fire up mail over SMTP with an SNMP agent, etc. the list goes on and on.

Network without DNS is un-useable. Apologies for my english, it is not my native language.

True, but I was talking more about creating DNS entries for NPM (and other package managers) and redirecting them to our internal services. I just thought it was funny to mention since we impersonate public sites on our internal air-gapped network.
