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.
How do you set up clients so they will always use the first one? I thought if a client knows 2 servers they will switch between them.
I plan to add a second Pihole at some point and keep them synced
Yeah, you can’t. There is no guarantee that clients will use dns servers in any particular order.
Are you using pihole to also create custom local DNS records?
Yes, mostly just the hostnames
