Listen on the port binding to bind_address.
If bind_address is set as "*" (default), the server will listen on all available addresses (both IPv4 and IPv6).
If bind_address is set as "0.0.0.0" (for IPv4) or "::" (for IPv6), the server will listen on all available addresses matching that IP type.
If bind_address is set to any valid address (e.g. "192.168.1.101", "::1", etc), the server will only listen on the interface with that addresses (or fail if no interface with the given address exists).
