Raspberry Pi – PiHole DNS Server NOTE: I had to disable the systemd-resolve service so that DNS requests where resolved by PiHole and not the default system service. $ sudo systemctl disable systemd-resolved.service $ sudo service systemd-resolved stop Running your own network wide DNS server can have its benefits. The reason for me setting this up is that I finally got fed up seeing large, in your face, adverts on my phone at home.
