Of the 128bit IPv6 address only 64bits are actually usable the "/64" is actually more similar to a "/32" host route in IPv4 land. To be correct a "/64" represents one LAN segement with maybe multiples hosts on it. This comes from the fact that the lower 64bits of a IPv6 address are autogenerated. rtsol (router solicitation) uses these lower 64bit. -- :wq Claudio
