Should I use a dedicated DHCP/DNS server hardware (lemmy.world)

My current setup has my DHCP + DNS on my Unifi USG. However, as I have all my apps hosted on a different server (unifi, plex, home assistant, NAS, etc.) I've ran into issues trying to get things set up.

Basically, Unifi needs to know where the unifi server is, but it's assigning the IP address to it.

Should I put DHCP+DNS onto it's own system? Should I put it on my current server? And any non-Pi recommendations for systems? (I've had the PI filesystem clobber itself too many times)

Edit: I'm starting to think that the real problem is having UNIFI on the same system as the server, as it prevents me reconfiguring any of the server routing information without also disconnecting unifi...

Edit 2: I'm going to try switching the server from a static DHCP lease to a static IP. If that's doesn't work, then I think I'll move the unifi server onto it's own system. Thanks!

Sidnenote about the PI filesystem self-clobbering: Are you running off of an SD card? Running off an external SSD is way more reliable in my experience. Even a decent USB stick tends to be better than micro-SD in the long run, but even the cheapest external SSD blows both of them out of the water. Since I switched my PIs over to that, they've never had any disk-related issues.

I've completely bricked two SD cards using a Pi. The USB option sounds interesting, I'll have to try it.

Grab this cable: https://www.amazon.com/gp/product/B00XLAZODE/ (make sure it's the USB 3.1 version, not the USB 3.0) then plug in any SATA device. you should be able to find a 512GB SATA SSD for less than $40.

Damn this is so much simpler than the USB 2 version I have from 8 years ago...
