Changed DNS IP4 over night on router


Two days the pihole works fine. Today I figured out that the DNS IP4 has changed from last digit 3 (which is the fixed IP of the raspi) to 4. All internet traffic and IP phone does not work. I re-entered the right number and it works again.

What could be the reason for this? Is it because the pihole starts again?



It’s because of the raspberry pi :slight_smile:
It doe snot have a static IP set-up (the one you need) and it’s getting it’s IP from the router via DHCP.

You can fix it by assigning a static IP to your pi:
