Do you use a telco/cableco provided modem? I was escalated through 3 tiers of support who all gave me different answers. I called to pick a fight over the fact that I live in an urban center, and while they advertise "90% IPv6 coverage on their residential network" I still don't have IPv6 access. I wanted to know what actions I could take to get IPv6. I knew that a competitor offered IPv6 (a friend just switched) and having IPv6 access would make it much easier to administer my servers w/o using a tunnel. - The first tier support told me my leased modem did support IPv6, but I'd need to buy a "business class" plan. This was a flat out lie, and in fact I "have" a business class plan at work. (Hint: it's the exact same modem, and we don't get an IPv6 allocation at the office.) - The second tier told me IPv6 wasn't available in my area, full stop. - The third tier [correctly] told me my modem doesn't support IPv6, and that a new one from an "approved list" would. (Though when I inquired about a specific model _from that list_ she told me it wasn't supported.) --- In the end I bought a modem from that list (the exact one she told me wouldn't work, hilariously enough) and IPv6 just started working out of the box. I really don't understand what the point of leasing a modem from a cableco is. I was operating under the assumption that they'd replace it when it was obsolete or in disrepair, but apparently "has IPv4 access" doesn't count as obsolete just yet. So if you want IPv6 access: a good place to start would be pestering your ISP and probably ditching your ISP provided gateway. As an added bonus I now save $10/mo on my bill.
