Re: [Xen-users] IPV4 is nearly depleted, are you ready for IPV6?

Well I think many IPv6 issues already have been fixed - the biggest

I would not like a solution that keeps us on IPv4 forever, because
many problems of IPv4 or unofficial extensions are now solved /
fully integrated into IPv6 - the protocol is cleaner and (without
any filtering) more secure than IPv4.
I think it will come - eventually. The problem we have at the moment
is that some many key players, specifically large consumer ISPs, just
aren't supporting it.
So we are still at the chicken or egg situation. The majority of
consumers can't use it because there isn't "plug and pray" support
from either their ISP or the budget router vendor. We can't expect
the masses to get down and dirty to setup 6in4 tunnels to IPv6
brokers in order to get access to something that for most of them
doesn't offer anything compelling.
At the same time, the large ISPs and consumer router manufacturers
see no demand and thus don't want to spend the money on something
that "no-one wants".
And a big part of the problem is NAT. Too many people think that NAT
is a) a good idea, and b) a solution. It's 'solved' the IPv4 address
shortage problem in so many eyes, and for so long, that it's taken
away a lot of the impetus to get IPv6 widely deployed.
The answer I had from my ISP last time I asked was that they had no
plans and it would be a hugely expensive project. Well duh, it will
be if you don't start now. Getting the core network IPv6 enabled
would be a good start - and then start making NEW stuff IPv6 enabled
would be a good second step. Done that way, the cost and risk could
be both reduced and spread - and one day people would suddenly
realise that IPv6 is here !
At which point I remember I still haven't done anything about using
my end of a 6in4 tunnel from HE :-/
