BIND vs NSD + Knot DNS
Self-host pick — both replace Cloudflare DNS (Authoritative DNS hosting).
Both BIND and NSD + Knot DNS self-host as a replacement for Cloudflare DNS (Authoritative DNS hosting). Pick BIND if you want a MPL-licensed codebase (MPL-2.0); pick NSD + Knot DNS for BSD (BSD-3-Clause). Both run in roughly the same cost bracket — $5/mo vps minimum; redundancy needs 2-3 boxes vs $5/mo vps minimum.

Good fit for
BIND
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.
NSD + Knot DNS
Authoritative-only deployments where minimal attack surface and high performance per CPU matter (TLDs, DNS providers).
Weak at:No bundled UI; less common in tutorials than BIND/PowerDNS.
