In reply to Peter Van Eynde.

About 32% of the external traffic was IPv6 which I believe means that between 32% and 53% of the traffic was available over v6.

If people on dual stack network were not using any v6, 60% of traffic would come from the v6 only network, it would mean 53% was available over v6 (32% of external out of 60% of internal).

If ratio was the same on both networks (i.e. all devices on the dualstack were connected over v6 for anything available on v6) it would mean only 32% was available over v6.﻿
