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?

Hi Beel,

That was unnecessary. Sorry I used an S instead of a Z.

Thanks for backing me up with an example of an organization with
competent network engineering.  Their ability to almost infinitely
leverage the existing rfc1918 address space to serve an appreciable
fraction of all Internet attached hosts is a real demonstration of the
possible.

Except they don't. One of the reasons you can't put vms in multiple
regions into the same VPC is they don't have enough IP addresses to
uniquely address the backend hosts in every region. They end up with a
squirrelly VPC peering thing they relies on multiple gateway hosts to
overcome the address partitioning from overlapping RFC1918.

In other words, it proves the exact opposite of your assertion.

Regards,
Bill Herrin
