But it shows that if you turn on IPv6 on the servers you will get
IPv6 traffic.  We are no longer is a world where turning on IPv6
got you a handful of connections.  There are billions of devices
that can talk IPv6 to you today the moment you allow them to.

Can all your customers talk IPv6 to you?  No.
It the proportion of customers that can talk IPv6 to you increasing?  Yes.
Is somewhere between 11-14% worldwide enough for you to invest the
time to turn on IPv6 enough?  It should be.
