Which is what's missing in the DNS where the reverse lookup fails;
likely, it's a bug that FreeBSD does not come with a caching DNS
server enabled by default, out of the box.
The FreeBSD library bug is that the /etc/hosts file entry:
::1
is not canonized before being compared, for the reverse lookup.
It can probably be worked around by spcifying:
0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1
as the left hand side for the IPv6 loopback address, instead of ::1,
in the /etc/hosts file. I don't recommend this, since it would not
encourage the author of the IPv6 resovler code to fix the bug they
introduced.
