That is true at least for 2.4.x. In 2.5.x I improved that code, plus it
reports on the dashboard if IPv6 is not available.

As for 2.4.x and older 2.5.x versions I would suggest to use netstat to
check the binds and/or configure them more explicitly by binding to ::
and 0.0.0.0 with two listen sockets. This is also required on systems
that do not support legacy IP over IPv6 or have it disabled.

With best regards,
