I’m about to throw my entire Pihole out the window (lemmy.ca)
submitted 1 year ago by [email protected] to c/[email protected]

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.

Then that’s likely your issue.

Your router occasionally gives out the ip of your pihole to someone else, and everything shuts the bed.

Try picking x.x.x.254 as the pihole address or x.x.x.2

Often routers won’t use either the top end or low end of the available addresses.

The machines on your network that are dhcp, do they go below 100? Do they go above 200?

You’re going to be guessing a little here.

What is your “net mask”

Ya I’m pretty sure you’re correct here and this is my issue. Since I’m not able to log into my router and define my dhcp range, I’ve picked an IP near the end of the range (254).

All my other devices are assigned .23, .25, etc.

Fun learning experience haha

Your ip-mask will tell you what IPs are accessible on the network

Likely goes nowhere because it’s probably 255.255.255.0 but it’s possible to be something else.

Ya it’s the 255 one. Thanks to all the help on the thread I’ve managed to set my server IP outside of the DHCP range (I think) so in theory my issue should be fixed. I’ll know in 90 days when the IP addresses are renewed.

Np, pay it forward to the next person that needs your help.
