Sounds like you already are and nobody is telling you that you can’t. It’s a rather silly way to over-complicate your life, but if you want to be on the wrong side of a direcTV commercial, nobody’s trying to stop you. > >> The routing problem might be real if everyone goes to PI, but I think that’s >> an unlikely scenario. > > Every scenario everyone has come up with is "unlikely".

Given that more than 50% of US mobile traffic is now IPv6, I find it hard to give credence to a claim of “not using”. It’s also north of 40% for US fixed wire line traffic. As I said, I don’t doubt that we may eventually run out. However, I doubt anyone alive today will still be alive when we do. Owen
