@GregAlexandre I don't recall the exact wording, but it is possible, however, it requires a support ticket, as it is a manual process for us. We do get these requests on a regular basis and usually handle them within one business day.
@GregAlexandre Where exactly do you see an issue with IPv6? As far as I know, then we support IPv6 everywhere in Production, and approx. 13-15% of all client traffic is IPv6 based.
