​
dns setup

Plan or apply CoreDNS setup for unicast DNS-SD discovery. Options:
  • --domain <domain>: wide-area discovery domain (for example fluffbuzz.internal)
  • --apply: install or update CoreDNS config and restart the service (requires sudo; macOS only)
What it shows:
  • resolved discovery domain
  • zone file path
  • current tailnet IPs
  • recommended fluffbuzz.json discovery config
  • the Tailscale Split DNS nameserver/domain values to set
Notes:
  • Without --apply, the command is a planning helper only and prints the recommended setup.
  • If --domain is omitted, FluffBuzz uses discovery.wideArea.domain from config.
  • --apply currently supports macOS only and expects Homebrew CoreDNS.
  • --apply bootstraps the zone file if needed, ensures the CoreDNS import stanza exists, and restarts the coredns brew service.
