<DIV><SPAN class=486121108-06052005><FONT face=Arial

<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>Following the
discussion about /48 boundaries I'd like a better definition of what a site
is.</FONT></SPAN></DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>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.</FONT></SPAN></DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>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.</FONT></SPAN></DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>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.</FONT></SPAN></DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>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.</FONT></SPAN></DIV>

<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>We can't decide how
many addresses to assign to a customer based on size or revenue.

<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>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.</FONT></SPAN></DIV>

<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>I also include my
suggestions based on where I'm coming from :-)</FONT></SPAN></DIV>
<DIV><SPAN class=486121108-06052005><FONT face=Arial size=2>/60 for home
networks (16 networks)<BR>/56 for enterprises (small/medium) (256
networks)<BR>/48 for large enterprises (65000 networks)<BR>/47 or more for "very
large subscribers"<BR>/64 for mobile phones (w/ bluetooth or 802.11b)<BR>/128
for dialup PC</FONT></SPAN></DIV>

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.
