Subject: [v6ops] Observation of /64s of cellular operators

In the place where I live, a majority of the main cellular operators
offer a /64 to the User Equipment.  This is public data.

There is some exception (operator Free) but the exception is not about
delivering a shorter or longer prefix to the smartphone; the exception
is about delivering or not delivering IPv6 connectivity to smartphone.
Once it is delivered, I suspect it will also be /64.

In other places, e.g. Reliance JIO operator in Asia, also the length is /64.

This situation (only a /64 per User Equipment) creates problems for
vehicular networks that I work with.
