Two questions...

1. How many on this list already have dual-stack or IPv6 only in operation?

2. If you are running IPv4 only, and a major service was to switch to IPv6
only,..
     a. How fast would you move to a dual-stack of IPv6 only?
     b. What would it impact your customers?
     c. How would it impact your business?
