Re: "DNS-4to6 automatic mapping" - No more DNS-ALGs & 6then4 DNS queries
Make all the distinguishing you wish.
The bottom line is that OpenBSD userland unconditionally enables IPv6
regardless if the kernel supports it or not. If there is no v6 default
route, v6 fails quickly and seamlessly back to v4 (telnet, ftp, ssh, etc)
and behaves sanely.
I do not see why mandating different is productive for a future of v6
deployment.
