Phil Sorber commented on TS-2158:
---------------------------------
He was using <phi> (as clarified in IRC) and it was picking the IPv6 link local
IP because this function didn't properly identify it as non-routable.
There is still the further question (which I think we decided yes to) of
whether we should give IPv6 preference anyway, since that is the standard when
dealing with dual stack.
But I have been thinking about this a little more, and the code separates out
loopback as well, so maybe this should be renamed to ats_is_ip_private() and
then we should also add ats_is_ip_linklocal() and then we can make
ats_is_ip_nonroutable() wrap all 3 of those. Thoughts?
> ats_is_ip_nonroutable does not properly handle link local addresser nor v6
> addresses
