Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

OP already said that their current DHCP solution (the router) can't push multiple DNS servers. Having a good secondary can be really helpful for things like power blips, maintenance windows, and cats pulling power cables. There are a few solutions that also do ad blocking that can make good secondaries
I don’t think anyone is arguing against dual DNS servers. The distinction being made is that a second DNS server is not a fallback. Most newbies think “secondary” means it will only be used when the primary is unavailable. That’s not true. A client is just as likely to use a secondary DNS as a primary. If only one DNS uses pihole, then the secondary will serve ads because it’s just calling the upstream DNS resolver.
Personally, I accomplished what OP is talking about with two rPis. First serves DCHP from 192.168.1.10 to .100, second serves .101 to .250. I send the two piholes as primary and secondary DNS. I also use Unbound as the upstream, but that is just personal preference.
Depending on the client, it can be. The Microsoft page pretty cleanly defines expected dns client behavior [https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/dns-client-resolution-timeouts#what-is-the-default-behavior-of-a-windows-7-or-windows-8-dns-client-when-two-dns-servers-are-configured-on-the-nic](Microsoft learn). There haven't been any published changes to this that I've seen, and it more or less matches my experience. Linux is a lawless land in this respect, but it really boils down to "it might", so caveat emptor there. That's also why I suggested a public ad blocking dns server as a secondary, in case multicast dns does its multicast dns thing
