If you have a large web site (say top 2000) or mail system ( or other
apps) then you will almost certainly have your connections going via a
load balancer.  You have specialized servers for front end, images,
database, data, caching, authentication etc. You'll probably have multiple
examples of each, load balanced so that if one goes down nobody notices.
Here is a simple example:

Creating a seperate instance or path though all that for IPv6 is probably
going to be hard if it is all setup for everything to go one way.

On the other hand if your load balancer is IPv6 aware then the stuff
behind it might not need to be since it can NAT incoming request to ipv4.
