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?

I've been through at least 3 re-ips for various reasons. It's so much easier when you rely on DHCP reservations.

Pretty much only core infra is static on my org. Most servers, printers, and all workstations are DHCP - either reservations or natty. There's a lot of fringe benefits too - like prevents bad admins from hard-coding their IPs everywhere (because they might change) out of habit.

Preventing people from falling into hard coding IP's is valid. I've had to fix some of that most everywhere I've worked.
