My particular "killer app" for dnsdist right now is at my house I have 2 machines running dnsdist, set to forward to my pihole by default with health checks. If the health checks fail, the dnsdist daemons failover to google/cloudflare/etc.

This lets me run a single instance of pihole (avoiding all the issues with trying to replicate configs across multiple pihole instances) and still having a solid backup if my pihole server goes down as it is by far the most likely piece of infra to just stop working.

I also use it to route requests to my internal authoritative servers and failover to my external secondary authoritative mirrors as needed. This lets me keep all my local traffic local and still have my external failover as a catch all if my homelab infra is down to my own screw ups or some hardware failures.
