For most real life scenarios, a Raspberry Pi would fit your needs with 2000
"typical" domain names.

The biggest determinant in performance is if your database can fit
everything in RAM and is happy with the amount of records. Below a few
million records, "this always works".

People often get very disappointing results with databases hosted far away
on overprovisioned cheap virtual servers, try not to do that.

Good luck!
