I have been running my home DNS on a pair of RaspberryPi’s for some time now. The main reason for running my own DNS server is to utilize the excellent pihole project to block 3rd-party ads from being served to my home network. I ansiblized the config files. It has been running great for a couple of months. Recently, I have acquired an orangepi, a RaspberryPi 3 and a new desktop.
