I’m about to throw my entire Pihole out the window (lemmy.ca)

Every month or so all my devices lose internet and the only way to connect them all back is to disconnect them from the DNS server that Pihole is running.

I set my Pihole to have a static IP but for some reason after around a month or maybe longer, it just fails. This has happened 4 times over the last while and the only fix is to essentially uninstall everything on my Pihole, disable it, and then reconfigure it from scratch again.

I’m not sure what’s going on so any help would be appreciated.

Just think of it as a routing optimisation that is only relevant for ipv4 networks.

Router simple, router need to make decisions quick, quickest decision is made when can smush the subnet mask against an IP address and determine if the computer is on a local network so router can send traffic direct or is on other network so router needs to send traffic to other router
