complicated and unjustified
compilcated ? no! the same as in ipv4
But I didn't say it was simple in IPv4
(adress space in v6 is *not* rare)
along time ago, there where some people who said the same sitting on the ipv4 world.
There is millions of /24 IPv4 There is more than a million of billions of /48 IPv6
not the same thing
it's the same, only the comma is on a different point.
There was less than 3 billions of human beings or so when IPv4 was created There is 6 billions of human beings today There will never be more than 30 billions of human beings on this planet (changing planet is not as easy as changing Internet Protocol) With the /48 model, infrastructure need no adress space (Nerim is an ISP, infrastructure is ONE /48, custommers will have 99.999% of the alocation) If you give 2 thousands of /48 per human beeing, you will have spare space.
No But paying somebody to change the adress space of the customer cost
the initional request of ip addresses doesn't cost anything in my company. we only bill when a customers want's an addional network.
But your competitors will give a /48 directly without charging. And it will cost them less time. They will not break the IAB recommendations (but you will).
IPv6 adress space costs *nothing*
IPv4 space costs *nothing*. did you pay diffrent prices @ ripe for diffrent ISP allocations ? /16 very cheap, only 500.000 Euro per year ? if you buy 2 * /16's you get one /20 for free!
Fixed costs (part of ISP job); and a big Cisco router costs much more than the RIPE fee. But IPv4 is rare -- Xavier Henner Responsable de l'exp�rimentation IPv6 Nerim -- Fournisseur d'acc�s � Internet URL: <http://www.nerim.net/>
