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.
