There is another case where the customer does not ask for it.  I don't
think Google or Facebook's or Bing's customers meaningfully asked for
v6, yet they did it.  Same thing with Verizon LTE. Maybe the Bing
folks can help you with internal strategies for getting support.

Nonexistent demand?  Let's bing it and decide

Interesting hits my query are






But, this is just the same old carping.  Skype / Microsoft should add
IPv6 support because it is the right thing to do for the Internet.
Microsoft, like Google and Facebook, was part of world v6 launch and
knows ipv6 is about making the internet better and bigger.

The Skype issue is so serious, that it is specifically blocking
IPv6-only architectures since it is THE most major app that breaks in
IPv6-only.  Skype is the killer app for 464XLAT ... which means that
since Skype refuses to evolve their product, the OS now has to have
hacks to fix it.
