How to create a pi-hole ad blocker with a Raspberry Pi
A pi-hole is a DNS based ad-blocker. You simply point either your router's DNS or individual device's DNS to its IP.
Use either a R-Pi, or create a simple Linux VM with 1 core and 1GB RAM.
Assign a static IP (via DHCP reservation) to your R-PI or VM in your router.
(Linux only) sudo apt-get install net-tools
curl -sSL https://install.pi-hole.net/ | bash
Point your router's DNS to your R-PI or VM.
