Some weeks back, I decided to set Pi-Hole (the DNS-based black hole for ads and other creepy requests) again on my home network. I already had an Ubuntu VM available. It only took minutes to get it going on that. I previously ran it on a Raspberry Pi Zero.
My Eero mesh network uses the Pi-Hole for DNS and Pi-Hole used OpenDNS for its DNS. About a week ago, my Ubuntu VM changed its static IP address unexpectedly and, in a hurry, I just restored Google DNS settings to it because I knew them (8.8.8.8, 8.8.4.4). But I’ll probably go back to OpenDNS, because no one on Earth should trust Google.
Pi-Hole is a wonderful product.
