Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

IDK about that angle of them not having/not able to use IPV4.

A Basic dig on their ASN's shows they have a crap ton of IPV4 registered.  Over 12 million on just ONE of their USA ID's (AS21928).  Granted, some (like AS393494, that appears to be tied to TVision) only have 60-70k... but who is to say how much is actively in use, and how much could be repurposed?

But they DO in fact have and use IPv4.  The question is why is it not implemented for home internet instead of the screwy XLAT464 crap.

 

Who knows why they still own these subnets.  Owning them, however, doesn't mean T-Mobile isn't an IPv6 network.  Indeed they are.  They completed the transition years ago.  XLAT464 is of course used for compatibility with IPv4.  Some of these IP's are needed for that.  At any rate, let's just say they would make the decision to switch back to IPv4, these block's of IP's wouldn't come close to the number of IP's needed to support IPv4 for all the devices on their network.  And the problem only gets worse as their network grows.
