Re: "DNS-4to6 automatic mapping" - No more DNS-ALGs & 6then4 DNS queries
What box? There is no box to enable v6 on OpenBSD. The only place
in OpenBSD that does not have v6 enabled by default is in a few install
media kernels, which do not have space for v6. The userland ftp utility,
used for retrieving images, fails most gracefully when given a hostname
that has both v4 and v6 addresses, it tries the v6, fails immediately,
and then uses the v4 address.
I guess you have not tried OpenBSD since you seem to think there are
options check boxes that enable/disable v6 entirely during the installation.
