Set coturn_public_ip6 in inventory to advertise IPv6 relay candidates (2nd external-ip) AND emit matching v6 denied-peer-ip ranges (::1, fe80::/10, fc00::/7) for SSRF parity with the v4 lockdown. Unset → byte-identical pure-IPv4 config as before, so it's zero-risk opt-in. Droplet now has IPv6 on; this makes the conf dual-stack-ready.
