How to detect if your devices are trying to circumvent your pihole

As I described in my previous blog post, you can set up a pi.hole DNS server to optimize your network traffic and your browsing experience. But not every device will be respecting your DHCP DNS settings it seems. Some devices have hardcoded DNS entries and just ignore your settings. Scott Helme wrote on his blog how to redirect those naughty devices and redirect their traffic to your pihole instead. But before we start doing that I was curious to find how many of those devices I actually had on my network.

Installing pihole on your Cloudkey gen2+

The other day I bought myself a Gen2 cloudkey plus from Ubiquiti and replace my old cloudkey. It comes installed with the Unifi SDN and the new Unifi Protect. The device looks really nice and has a little display which shows you information about the applications running on the device. Since I have been playing with pi-hole lately on one of my Raspberry Pi’s, I was wondering if I could install pi-hole on the cloudkey so I would have everything from my network on a central place.
