Switching from Cloudflare DNS to BIND

Install `bind9` from your distro. For each zone, write a BIND zone file at `/etc/bind/zones/example.com.zone` with SOA, NS, A, MX records — Cloudflare zone export via `cf-terraforming` or the API → BIND format. Configure `/etc/bind/named.conf.local` with each zone definition. Test with `dig @localhost example.com`. Update registrar NS records to point at your BIND servers.

Good fit for: Sysadmins who want the reference DNS implementation and are comfortable with text-file zone management.
Weak at: No built-in web UI; zone-file editing is unforgiving (missing dot, fat-finger TTL); no API without bolt-ons.
