Windows 11 Firefox sends excessive DNS requests

Hi All,

I am having the same issue on my network. This started to happen recently enough, in the past week or so. I have been running pihole successfully in my network for over an year and only in the past week or so that this issue started to affect my network.
I see firefox hitting all of my internal services trying to resolve it time over time.

I have always hosted services on my local network with a domain.pri naming convention.
Pihole is running on a Ubuntu VM on my server hosted at home, which was always the case and it was never a problem until now.
Pihole serves as local dns for my hosted servers.

Does anyone have any guidance on how to solve this? there was no major changes on my network recently.
The computer with firefox that is hitting the pihole hard is running Windows 11, fully patched.
I've discovered that is firefox due someone recommendation on another post to use DNSLookupView to find out the DNS queries.

When tailing the pihole.log I do see similar requests as OP posted above.

I've generated a Debug token if it is any help
https://tricorder.pi-hole.net/n3pxFiDc/

Any way for me to go from here?

Thank you in advance

Hi Mayrink,

Access the pihole's web interface using it's IP address (192.168.xxx.xxx), not it's hostname (pi.hole).

The weird thing is,. I always accessed it via hostname which is a custom local dns I've created, and it has been working like this for over an year.
And the issue is with other servers in my network that that is having the bigger amount of queries.
Has something changed recently that is causing this?

I've split your post to a separate topic - as ETA_2024's topic was marked as solved, and as that solution is not working for you, you are observing a separate issue, apparently.

Do you have a machine running Firefox 24/7?

Run from your Pi-hole at a time where you've observed a recent surge in requests, what's the output of:

echo ">stats >quit" | nc localhost 4711

echo ">top-clients >quit" | nc localhost 4711

echo ">top-domains >quit" | nc localhost 4711

echo ">top-ads >quit" | nc localhost 4711
