Under VPN 0, which vBond system configuration option allows a routable public IP even if DNS name, hostname, or IP are omitted?

The local option under VPN 0's vBond system configuration allows you to specify a routable public IP address for the vBond orchestrator, even if other identification methods like DNS name, hostname, or IP are not explicitly configured. This is crucial for vEdge routers to discover and connect to the vBond, especially in scenarios where dynamic DNS or private IP addresses are not suitable for initial reachability. The WAN option is a general interface configuration, not specific to vBond discovery. dns-name explicitly uses a DNS name for vBond discovery. vbond-only is not a valid configuration option for specifying a routable IP under VPN 0.
