It is does not appear realistic to expect ISPs to "interview" each customer and ask them whether they intend to subnet or not.
so, you think it's not realistic to ask the customer if he intends to subnet or not ?
ipv4 view: why not to give all your dialup customers in ipv4 per default a /28 delegation, and the customer decides to do NAT, all in one subnet, or more subnets ?
No : we have not enough space on v4 The RIPE-NCC will not agree Nerim is a small ISP but we give a static IPv4 adress to custommers if they want. If a custommer need a /29 or /28, and can justify it, we send the request to RIPE-NCC All of this costs time.
no, i would give everyone /64 per default, unless the customer says, "no, i want to do subneting", then i will give him a /48 without discussion.
complicated and unjustified (adress space in v6 is *not* rare)
Everyone will probably end up with a /48: it reduces costs for the ISP.
ipv4 view: some years ago,....: Everyone will probably end up with a /24 There is millions of /24 IPv4 There is more than a million of billions of /48 IPv6
not the same thing
hm...i think the cost point isn't a good argument, sorry. does it cost so much to do subnetting ? you have one block with /64 delegations and one with /48's.
No But paying somebody to change the adress space of the customer cost IPv6 adress space costs *nothing* -- Xavier Henner Responsable de l'exp�rimentation IPv6 Nerim -- Fournisseur d'acc�s � Internet URL: <http://www.nerim.net/>
