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.
