We had procured a 4G data card through Verizon for some remote administration needs - and had static IP enabled for the data card as such.
Prior to the static IP being enabled, I had observed a dual-stack IPv4 and IPv6 configuration: A dynamic and NAT'd IPv4 address, as well as a presumed-dynamic and public IPv6 address. (The distinction of the IPv4 address being static vs. dynamic isn't nearly as critical as to whether it is public or NAT'd, with a public, non-NAT'd address being required for accepting remote connections for purposes of remote administration, security cameras, etc.) With the conversion to a static and public IPv4 address, we are no longer being issued an IPv6 address (at all / of any type). Is there any available option here for having a dual-stacked IPv6 address along with a "static" IPv4? I'm not overly concerned as to whether the IPv6 address would also be static or not.
I am aware of some workarounds for this - such as 6to4 or using an IPv6 tunnel broker - but would much prefer at least the same native level of IPv6 that is available as dual-stack with dynamic / NAT'd IPv4 addresses, if possible. (Less encapsulation and better performance, etc.)
I previously spoke with Verizon Technical Support and was simply told that this was not an option - but am posting here in case anyone knows differently, or to track progress on this in case this is changed in the future.
