Hi ALTOers, This is the revised version of the document, addressing comments and issues identified by Danny, Jensen, Kai, authors and some comments from our wonderful chairs.
One "interesting" change is 2001:db8::1:2345:6789:abcd -> 2001:db8::1234:5678 to make sure that the ipv6 range is within the range of Table 25 of RFC 6890.
