Currently have nice long docker compose file that hosts my PiHole V6 container (along with a bunch of other containers) however, reason i ask this question is because whenever I go to pull an updated image and recreate the container I experience about 20 minutes of no DNS resolution which to my knowledge is due to the NTP clock being out of sync.
What’s the best way to host a DNS sinkhole/resolver that can mitigate this issue?
Was thinking of utilizing Proxmox & LXC but I suspect I’ll get the same experience.
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.](https://discourse.pi-hole.net/t/primary-vs-secondary-dns/1536/2)
[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].](https://discourse.pi-hole.net/t/secondary-dns-server-for-dhcp/1874)
The **ONLY** DNS server you should have set on your network is a/the PiHole(s).
