[ipv6-wg at ripe.net] What is a site?

 In your previous mail you wrote:

   I also include my suggestions based on where I'm coming from :-)
   /60 for home networks (16 networks)

=> there are two reasons to use subnetting:
 - organization: this is in fact easy because stable/predictable and
   always handled by the manager
 - uncompatible links (like 802.11 and 1394): this will happen for
   home networking which should be handled automatically. With a
   hierarchical topology, the hD ratio should be good (~.8), with
   a mesh topology, random allocation of SLAs give a .5 value
   (cf birthday proble) for the HD ratio.
   Today we don't know how many links we'll get at the average but
   IMHO it should be 10~20 so /60 is clearly too small.
BTW the DHCPv6 Prefix Delegation will be very nice because it can
negociate the really needed prefix length. I believe it'll save us
for the home network case, which will be as I explained an hour ago
the critical one because of its very large number.
