Which vBond system configuration under VPN 0 allows for a routable public IP address even if the DNS name, hostname, or IP address of the vBond orchestrator are omitted?

The 'WAN' keyword is not a standard configuration option for specifying a vBond's public reachability in this context; 'WAN' typically refers to the general wide area network.

The 'vbond <IP address> local' command under the vBond's system configuration in VPN 0 allows the vBond orchestrator to announce its locally configured interface IP address as its public-facing routable IP, enabling connectivity without relying on a separate DNS name or specific public IP configuration.

The 'dns-name' option is used to specify a DNS hostname for vBond, requiring DNS resolution, which contradicts the scenario where DNS name/hostname are omitted.

'vbond-only' is not a recognized keyword for specifying how vBond announces its public reachability.
