I have Pi Hole v5.1 on my network doing DHCP and DNS. I used the web interface "disable" function this morning, instead of disabling ad blocking it seemed to completely disable DNS, meaning I couldn't resolve IP addresses.


Can anyone else reproduce this before I report a bug? It might be dependent on using Pi Hole DHCP. I use Pi Hole DHCP as the Fritzbox doesn't delegate IPv6 properly.

Can't reproduce. My set up isn't 100% the same as yours. Running the same versions, however, I use my router for DHCP and run Pihole from docker (on a Raspberry Pi).

 

When I disabled Pihole my first attempt to connect to a website timed out and I though "oh...it is a problem he's reporting" but second attempt and other websites worked fine. So may have just been a glitch in the matrix. Adverts were definitely disabled too.

Have you set both your primary and secondary to the Pihole?

Thanks @nzkc, I'll have a go on my main computer this evening then, could be some other network weirdness going on.

Pi Hole is doing DHCP and only hands out a primary AFAIK.

The reason I asked is that with a secondary not set to the Pihole you're getting a lot of your DNS queries via the secondary as a matter of course. The names "primary" and "secondary" are misleading, it's really just "option 1" and "option 2". So if @timmmay has primary and secondary set to the Pihole but you have primary = Pihole secondary = something else, you wouldn't see the issue because some of your queries are being sent to option 1 and some to option 2, which means with retries you'll eventually query the non-Pihole source and the name will resolve.

In my ethernet settings TCP has "use DHCP set". ipconfig/all is showing only a single DNS server. So I don't think it's that, thanks.

Bit late on the replies...

Like Timmmay I have just the pihole set as my only dns server. As mentioned that's configured by the router that is my dhcp server too.

I tried this on my main computer, same behavior. I rebooted the Pi, problem solved.

 

That's a weird one. Thanks all!
