Hy everyone, I have a PiHole instance running on my home server, and I changed my router (Fritz box) DNS in order to use my PiHole. Everything runs great.
I was wondering if I can put another DNS provider on my “alternative DNS server” in my router, in order to have a fallback alternative in case my server is down, or if I should avoid it.
I’m asking this because I don’t know if the request will be handled in parallel between the two DNS provider (that would make my PiHole useless) or not. Thank you.
How do you manage automatically transferring the ip of the main rpi to the backup rpi when the first disappears?
Keepalived
clone the Mac address
Don’t you then run into MAC conflicts?
How do you keep both on the network?
I’m just spit balling here: backup pi pings munute-ly main pi. if main pi is down 2 pings, it resets Mac and reboots network interface.
Then when the main PI returns it creates a conflict…
