Hi.
 
Following the discussion about /48 boundaries I'd like a better definition of what a site is.
 
My definition of an end-user site is the office where we (MCI/UUNET) install a circuit. This could be a large office or a small bransch office or anything in between.
Each office is handled separately and they request IPv4 addresses per office. Adopting this to IPv6 it would mean that each office would get a /48. This is too much for many of them.
Approx. 80-90% of our sites request 32 IP-addresses or less and most likely only subnet it 2 or 4 times if they ever subnet it.
 
Furthermore we never get a complete network design for all branch offices if the customer is transnational  or even national so we can't really assign a /48 to the customer for him to subnet among his offices. We can of course change our procedures to accomomodate thisbut this will make things a lot more difficult for us as a LIR and also the customer.
 
We can't decide how many addresses to assign to a customer based on size or revenue.
 
What I want is a clear definition of what a site is by having more catagories. but I don't want a floating boundary as catagories do simplyfies things.
 
I also include my suggestions based on where I'm coming from :-)
/60 for home networks (16 networks)
/56 for enterprises (small/medium) (256 networks)
/48 for large enterprises (65000 networks)
/47 or more for "very large subscribers"
/64 for mobile phones (w/ bluetooth or 802.11b)
/128 for dialup PC
 
Please note that I'm not a routing expert nor am I a experienced in the complete IPv6 concept with mobil users and consumers goods etc. My main area is IP-address administration. I administrate IP-networks for MCI/UUNET in almost all of Europe except DE, AT and CH.
 
I haven't read the RFC's related to this so my mind is wide open ;-)
