I have a FreeBSD 8.2-STABLE amd64.

Network:
vlan300: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        description: Uplink_1
	inet
	inet6	

vlan400: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        description: Uplink_2
	inet
	inet6	

vlan100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        description: Internal_LAN
	inet
        inet6 2001:67c:21f0::ffff prefixlen 64

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
        options=3<RXCSUM,TXCSUM>
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x9
        inet6 2001:67c:21f0:f::1 prefixlen 64
        nd6 options=3<PERFORMNUD,ACCEPT_RTADV>

Some services, such as named, refused to use ipv6 with lo0.
Option
    query-source-v6 address 2001:67c:21f0::1;
makes a mistake and named service will not start.
Problems with the ipv6 address are on vlan100 - no.

P.S. BIND 9.9.2-P1
