We may even have a switch that controls "use probes that think they can do v6 but it doesn't really work" to check the corner cases. If there's a need for such thing. (Is that operationally useful? Or research only?)
Can you see probes that claim to have working IPv4, but haven't?
With enough probes/locations, we can see many kinds of corner cases. I'm sure we have probes in this condition...
AKA: is your controller infrastructure reachable over IPv6, and will the probes use it?
Short version: yes, all of our infrastructure is fully dual stack, without exceptions. The trick that we have to apply is how to reliably know if the probe can actually use IPv6 and/or IPv4. For this, we'll use results of real life measurements. Robert
