I have an asus router with a pi-hole on the network.
I was doing some work on my server and noticed that when pi-hole was down, I couldn’t access the internet. I was looking for some ideas online how to deal with this, but they said to have a second pihole on the network in case one is offline. Is that the only way to do it? Is there any way to have the network go back to normal if the pihole is offline?
Primary and secondary dns is not a thing. There is no priority for DNS. Depending on the device it will use ether address and will only try the other on failure.
Windows calls them ‘preferred’ and ‘alternate’ DNS servers. That roughly translates to primary/secondary.
It does not.
Yeah, that’s how they are named, my experience showed that the devices used whichever of the two they wanted.
