If IPv6 is tunneled through IPv4 in such a way that the ISP doesn't have to do anything special, then I suspect you wouldn't get charged extra. However, if an ISP has to run two logical networks as you do with the dual stack strategy, there will be additional costs in terms of hardware/software upgrades, technical support, troubleshooting, etc. I would think it fair that those expenses would be reimbursed somehow, perhaps with a bit extra to cover the cost of further upgrades. But then again, I don't run an ISP.

Do we charge to our customers when we solve a bug or problem in our network?
I suppose it depends on whether or not everyone agrees that the bug or problem exists and the solution proposed addresses that bug or problem.

IPv6 was invented to solve a "bug" in IPv4: The lack of enough addresses.
Actually, according to section 5.1 of RFC 1726:

The initial, motivating, purpose of the IPng effort is to allow
the Internet to grow beyond the size constraints imposed by the
current IPv4 addressing and routing technologies.

Both aspects of scaling are important. If we can't route then
connecting all these hosts is worthless, but without connected
hosts, there's no point in routing, so we must scale in both

Unfortunately, it would seem the "and routing" part was forgotten.

In my opinion, the real "bug" of IPv4 was the overloading of the routing locator and the end point identifier into the same protocol field. IPv6, of course, drove into the same swamp (yelling "me too, me too", with apologies to Dave Clark) and efforts like shim6 are hacks to get around this (now obvious) problem.

Of course, now IPv6 could bring extra features, and we should take the
opportunity to make new business based on that. The existence of an
"unlimited" addressing space for every customer
I _really_ wish people would stop saying '"unlimited"' or 'almost infinite' when talking about IPv6 address space. It simply isn't true, even in the theoretical sense, and particularly given how address space is being allocated now. It also gives many people the wrong impression: that IPv6 addresses will mean every grain of sand in the Universe (or whatever) can have portable address space.

itself will allow to create
new services and apps (unfortunately still to come, and that's the main
issue), which we will be able to charge for.
Maybe it's just me, but I suspect any service that would be compelling enough, in a business sense, to drive significant IPv6 deployment would also be implementable in some way in IPv4.

Also that will generate extra bandwidth demand, which we will also charge
My impression is that most of the folks who provide bit pipes really want to provide enhanced services, not driving to the bottom of commodity pricing.

Of course, at the end is a competition problem. If some carriers/ ISPs don't
charge for IPv6 service, may be others will need to same if they want to
stay in the market.
Very true. However, if carriers/ISPs don't recover their costs, they'll probably not be around very long to compete.

(speaking for myself only, of course)
