Only if you have addresses on it. Point is that you haven't any if
autoconf is used (no manually configured addresses) and carrier is down
(no cable or smth). Even link-local address is created after first
carrier up event.
And problem isn't specific to IPv6, there is same problem with IPv4. For
example if carrier aware network configuration method is used (as
nowadays common Networkmanager is).
