 AFAIK, this is no longer a problem in 9.0-RELEASE or in HEAD.
 
 The cause for this number of misses is absense of a route for
 IPv4 mapped block in IPv6 routing table.
 
 Here it is:
 
 # netstat -rn -f inet6 
 Routing tables
 
 Internet6:
 Destination                       Gateway                       Flags      Netif Expire
 ::/96                             ::1                           UGRS        lo0
 
 Some rc.d script installs this prefix in 9.0 and 10.0. If it hasn't
 been merged to stable/8, then it needs to be found and merged.
