Only if you enable IPv6.  ie. you put:

    ipv6_enable="YES"

into /etc/rc.conf.  That will cause each of your interfaces to have at least
a link-local IPv6 address configured, and lo0 will get the ::1 address applied
to it.  See /etc/rc.d/ip6addrctl /etc/rc.d/network_ipv6 for the gory details.

	Cheers,
