`openclaw dns`

DNS helpers for wide-area discovery (Tailscale + CoreDNS). Currently macOS + Homebrew CoreDNS only.

`dns setup`

Plan or apply CoreDNS setup for unicast DNS-SD discovery.

bash

openclaw dns setup
openclaw dns setup --domain openclaw.internal
openclaw dns setup --apply

Option	Effect
`--domain <domain>`	Wide-area discovery domain (for example `openclaw.internal`).
`--apply`	Install/update CoreDNS config and (re)start the service. Requires sudo, macOS only.

Without --domain, OpenClaw uses discovery.wideArea.domain from config.

Without --apply, the command only prints:

Resolved discovery domain and zone file path
Current tailnet IPs
Recommended openclaw.json discovery config
Tailscale Split DNS nameserver/domain values to set in the Tailscale admin console

With --apply (macOS only, requires Homebrew CoreDNS):
