I'm not suggesting cloudflare or public cloud by any means. It is not hard to run your own infrastructure on a small scale. However, you can play around with k8s/k3s without making it the lynchpin of the network infrastructure. I mentioned BIND being the reference implementation for a reason. Every single DNS feature will be supported in BIND. In X years when something new and cool comes and/or k8s/k3 becomes somewhat "legacy" and people move onto the "next" infrastructure, CoreDNS has a very real chance of becoming something like Designate. It works. It's fine. BIND will keep ticking. I haven't had to adjust my named.conf (other than adding hooks for things like the sig-external-dns addon) in over a decade. Do whatever you want with most of it. DNS in particular should be boring, stable, and able to run on a potato.
