Um, have you heard of dual stack? My Windows XP does it quite

Vista will do IPv4/IPv6 dual stack transparently without any command-line
enabling.
How does your ISP handle this?
They could do so (when they implement IPv6) by running dual-stack routers.
How much extra does your ISP charge you for IPv6 support?
My ISP doesn't yet provide IPv6 support. But at some point they (or
another ISP) will.
As I argued in another message, IMO ISPs will not be able to charge extra
for an IPv6 /64.
A /64 is a criminal waste of address space; they _should_ charge extra
for that.
I don't think you understand exponential math as it applies to IPv6.
IPv6 was specifically designed to make this possible. With /48
assignments and an HD ratio of .94, projections indicate a ~500 year
lifetime to exhaust the IPv6 address space.
That gives you basically as many hosts as your
routing/switching gear can handle on a single subnet (as you won't be able
to put 2^64 hosts on a single broadcast domain).
And even with a million hosts, you'll be wasting fully
99.9999999999945% of the /64.
Yep. And since there are about 18,446,744,073,709,600,000 /64's, such
wastage is not a problem. IPv6 was *designed* to make sure that address
space conservation is *not* required.
Do you see why IPv6 address space will soon be exhausted?
If you consider hundreds of years "soon", then sure.
As long as you already have v6-capable gear, enabling IPv6 shouldn't be
significantly more expensive than running v4. IMO it doesn't make sense
to try to run v6 on gear that only supports v4, but since pretty much all
new gear supports v6 now, folks should be able to gradually turn on v6 as
appropriate in their networks.
When did all applications become capable of handling IPv6?
They don't need to be. For the life of any existing applications, IPv4
connectivity will still be available in some fashion.
All the ones I've seen charge a small premium for additional IP space,
but it's never more than about a 50% premium.
Fifty percent is a small premium?
No, usually it's a lot less than 50%. More typical is like $5/mo extra
for additional IP(s).
