I just ensured my rc.conf didn't have
ipv6_enable="YES"
dropped to single user mode and came back up and it appears there is
still support for IPv6
> netstat -anf inet6
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)
tcp6 0 0 *.22 *.* LISTEN
There also doesn't seem to be anything in `sysctl -a', so I would
imagine you will have to rebuild the kernel with:
options INET6
commented out or removed.
Hope this helps.
