% ident /usr/src/etc/defaults/rc.conf=20
/usr/src/etc/defaults/rc.conf:
     $FreeBSD: head/etc/defaults/rc.conf 197619 2009-09-29 16:49:10Z dougb $
% grep ipv6_network_interfaces /usr/src/etc/defaults/rc.conf
ipv6_network_interfaces=3D"none"	# List of IPv6 network interfaces
#ipv6_network_interfaces=3D"ed0 ep0"	# Examples for router
% grep ipv6_prefer /usr/src/etc/defaults/rc.conf=20
ipv6_prefer=3D"NO"	# Use IPv6 when both IPv4 and IPv6 can be used

Does mean that IPv6 is disabled by default?  Who knows?  There is no
coherent explanation *anywhere* of what these variables mean, and
rc.conf(5) does not mention them at all.  In fact, the first hit for
"ipv6" in rc.conf(5) is this:

     ipv6_enable
                 (bool) Enable support for IPv6 networking.  Note that this
                 requires that the kernel has been compiled with options
                 INET6.
