No, what I've added are following items. They are:
- 6to4 address mapped from 224.0.0.0/4
- 6to4 address mapped from 127.0.0.0/8
- 6to4 address mapped from 0.0.0.0/32
- 6to4 address mapped from 255.255.255.255/32
they are pretty bogus and should not be sent to the wire from
any of IPv6 node (127.0.0.0/8 may be okay, but looks pretty strange).
