[6bone] v6 and ADSL

Are you an isp like entity? Sounds like it. Do you have 200 customers (or
plan on having such in 2 years?) possibly.
You should consider getting your own allocation of a /48.
Allocating /80's to clients is _not_ recommended. It breaks the spirit of
IPv6 allocation. Using point-to-point IP's is not strictly necessary with
most IPv6 implementations, so long as there is a global ip on either end.
But you can easily do the point-to-ponit IP's in one /64 and then allocate
/48's to each customer if you have your own /32.
Again, allocating /80's is not what I would recommend.
I'm prep'ing to upgrade a cisco to v6 capable ios, at which time I'll be able
to serve myself and others native v6 over adsl, no 6to4 involved. In the
future, there will be a /32 allocated, and assigning /48's to customers will
be easy. Getting them to use them is the hard part *grin* but I expect a few
will want to use them, including myself. I'll help my provider be the only
isp in the city that will provide native IPv6, which I hope will benifit them
more than I or they realize *grin*.
Anybody in the OKC area ready for native IPv6 over adsl in the next 6 months?

| Firstly, thanks to everyone for your speedy comments.
|
| I guess I should clarify what I'm wanting to do. I'm planning on obtaining a
| /48 from a Tier1 isp here in Australia, then divde that both into point to
| point links for our client's dsl tails, and /64 or /80 allocations for the
| clients own internal use.
| I know the cisco 827 would be fairly ideal to use as far as native
| connectivity goes, but it is fairly expensive when compared with other
| broadband routers on the market that small to medium sized businesses would
| use. Also, I'm not too sure what IOS it would need, and if thats
| commercially available. Anyone know of more affordable equivilants?
|
| The alternative is to run some sort of 6-in-4 tunnelling... again, having a
| supportable CPE solution would be best... I've even tossed up the idea of
| setting cheap/small intel box running linux of some sort... :-\ but the more
| professional the better.
|
| any thoughts?
| Dan
