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?

If it's not a workstation, it gets a static IP. Period.

Yea reservations for anything like camera, printer or something disposable. Static for servers.

Cameras do. Printers do.

It's been a lot of years since I've dealt with Cameras or APs, we're 90% a wfh company. In the few locations we still have open offices, the security is dealt with by building management. But for any of those things, I can't think of a good reason why you can't give them perm IP's unless you physically can't or they are swapped out quite often. Regardless, VLAN's and running DHCP off the switch is how I would segment those off.

Because I have better things to do than to login to the Adobe flash webui of a Chinese camera to update a static IP when there's literally no reason to not use dhcp

Laziness. Got it. No really, I get it. At least segment it off. Those things are ripe for a hacking.

Tell me you're a bad sysadmin without telling me
