Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I've set my secondary DNS to cloudflare, and my pihole still blocked ads for me. I assumed the secondary DNS server is used only if the primary can't be pinged. But i haven't actually looked into it.
I have two piholes, and sometimes both will receive requests at the same time, if there’s a lot of traffic.
Yeah this is what I do.
Putting Cloudflare as my secondary would allow some requests to get through and then often the device whose requests went to Cloudflare would continue using Cloudflare for a while.
The best solution I found was to run a second Pihole and use it as the secondary.
You can use something like orbital sync to keep them syncronized
Pretty much. Not sure how the router determines which DNS to use, but mine seems to latch onto whichever one serves up results the fastest, which would inevitably be cloudflare direct after the pihole returns enough blocks.
So I use a Raspberry Pi Zero W as a dedicated pihole, and my Pi 4 seedbox acts as its own pihole and as a redundant backup. Then use gravity-sync from the Zero to the 4 to mirror the settings.
Another cool trick is using tailscale to ensure your portable devices always can access your Pihole(s) from anywhere and then setting those server's tailscale addresses as your DNS servers in tailscale.
This way you can always use your DNS from anywhere, even on cell data or on public networks
I keep a third instance of Pihole running on a VPS and use it as the first DNS server in tailscale so it will resolve a bit faster than my local DNS servers when I'm away from home
Huh, I’ll definitely look into that. Both times I tried to route external pihole access, somehow other mystery services found it and it slowed to a crawl from getting absolutely pounded by requests not from me. Thanks for that tip!
Afaik there is no primary and secondary, you cant tell which one to use. Its best to have 2 piholes, but having 2nd DNS set to nextdns or something like that should be fine if you cant run 2 instances, probably not the best setup tho
When it comes to a “secondary”DNS... there is nothing like a primary and secondary DNS server. These indications are quite misleading but many systems adopted it this way. Pihole only list the DNS servers as primary and secondary, because this is what the providers write on their pages. The bad phrasing is supported especially by how Windows handles it.
Most operating systems implement DNS servers as alternatives, not as fallbacks, i.e. they will query any of both servers from time to time, so it is quite likely that you will loose your Pi-hole filtering capabilities (at least partially) [if you specify a secondary DNS server on your network].
The ONLY DNS server you should have set on your network is a/the PiHole(s).
Thanks for the clarification. I'll be updating my settings.
