What is the Preferred DNS?

i have been using Cloudflare DNS, is there a better or more preferred one to use. if i change the DNS from the web login do i just click save and we are good?

Thank you

You will have to decide which public server best meets your needs.

Or, run your own and avoid third party providers completely:


what are the differences between the 3 Quad9's how do i know what one to select? Also as there are 4 boxes do i have to put check in all 4 of the boxes per dns on the web interface or jus the on under 1Pv4?

We provide a description next to each. Decide if you want DNSSEC, ECS, etc.

If you aren't using IPv6 then select the IPv4 servers only.

sorry i guess that was a dumb question, but i just don't understand the difference even after reading those. i noticed that switching to the quad9 ads are appearing in my ios apps where they didn't on Cloudflare. i am just tying to find the best one as i have only used cloudflare.

Thank you

Try them all and see which works best for you.

i feel like something isn't working correctly:

Thank you

You have zero domains on blocklist. Rebuild gravity with pihole -g or using the web admin GUI tools menu.

hmmm how did that get messed up showing this:

pi@raspberrypi:~ $ pihole -g
[i] Neutrino emissions detected...
[✗] Pulling blocklist source list into range
[i] No source list found, or it is empty

[i] Building tree...
[✗] Unable to build gravity tree in /etc/pihole/gravity_temp.db
Error: no such table: main.gravity
[i] Number of gravity domains: 0 (0 unique domains)
[i] Number of exact blacklisted domains: 0
[i] Number of regex blacklist filters: 0
[i] Number of exact whitelisted domains: 0
[i] Number of regex whitelist filters: 0

Thank you

Please generate a debug log, upload it when prompted and post the token here.

Your debug token is: https://tricorder.pi-hole.net/qoj83d89bx

You have 3 clients assigned to group 3, and no blocking assigned to that group.

But, you also have the default group disabled, and all the blocking is assigned to that group. As a result, nothing is blocked for any client. Enable the default group and rebuild gravity.

ok, i guess i have no idea what i am doing. i am trying to have the pi-hole on for everything on the network except the devices below.

Thank you

ok, this correct:

Thank you

That looks like what you want.
