Host is the local interface on which the server listens for Binding Requests. Leave it empty (or set to 0.0.0.0 for IPv4 / :: for IPv6) to bind every available interface, or set it to a specific address to restrict the listener to a single NIC. To expose the server simultaneously on several interfaces use AddBinding instead. Host is also used by some STUN attributes (such as SOURCE-ADDRESS / RESPONSE-ORIGIN) when they are enabled in STUNOptions.
