a ram drive is volatile memory. you can get higher performance out of DRAM chips attached to the CPU memory controller, versus putting them behind the PCIe bus using NVME. for applications that only work with file systems, a RAM drive works around that limitation. so, why bother?

whatever it is you’re trying to do, be careful that your pi-hole DNS on port 53 is not exposed to the internet. otherwise your server will be abused for DDOS amplification attacks.

Nothing would stop you from running a DNS server on Mars and handling requests locally.
