I noted this in my introduction. It could be changed to wildcard, but it may lead to intermittent failures on macOS which is usually rectified by explicitly using loopback address to avoid some idiosyncratic port allocation.

It is note, also, that the UDP port is hardcoded to one from the IANA reserve port range, but uses an unassigned port in that range.
