Not that it particularly matters for just queries. The problem is that DHCP can only be enabled on one host. If that one fails then devices can’t get on to the network themselves. I’d like to know a good way to have a failover DHCP server - my janky cronjob isn’t great.
Where do you do DHCP? I had a primary pihole with DHCP enabled and a secondary with a cron job that enabled DHCP if the primary was down or disabled it if the primary was working. The cron job did sync DHCP leases from one to the other but it was a bit janky. I tried to update the secondary to pihole v6 and hosed it so I have no backup for now. I’d like to re-image the secondary and get a better setup - when I have time.
Edit to say I really wanted to try keepalived - that’s really cool to fail over without clients noticing.
Solar photovoltaic doesn’t involve steam. We can be solarpunk as well!
I guess hydro-power uses steam in the global water cycle so I’ll give you that. Radio-Thermal Generators are all solid state, but not much power on earth comes from them.
How do the DNS servers resolve local hostnames then? The pihole DHCP integration adds local hostnames to DNS when they are assigned an address. If there’s two DHCP servers handing out leases, presumable only one would be accepted, how then would the DNS servers sync those names?
I think I had my secondary pihole resolve local names from the primary, and leases were copied over on a cronjob in case the secondary DHCP server had to be enabled.
