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?
Umm, yea, if your DNS server is offline, how do your machines know how to resolve DNS names to IP addresses?
Which is why IP config has the capability for multiple DNS servers.
If this is surprising, you may wanna read up on your networking.
Why the extra snark? This person is asking a question. Easy to argue that he is trying to learn more about networking, why ostracize?
I think he realized that, he’s looking for a solution though.
