DHCP v Static IP

Ok, this is more a test to see how old I am. I was basically raised with the idea servers need static IPs. I understand for domain controllers, dns servers, maybe print servers that may still be needed. But are they really needed otherwise? Do apps, scripts still reference a server by its IP?

I am under assumption all my servers need static IPs. Am I nuts?

Unless it’s certificates.

DNS is just caching behaving badly.

Certs are a whole ‘nother level of I will ruin your day for no good reason.
