> Starlink User Terminal hands out a /56 prefix (via DHCPv6) and mine has not changed in all that time so I wouldn't call it dynamic.

Unless the service explicitly states that your subnet is your or yours alone you should assume it's dynamic.

If you start relying on the prefix not ever changing you might have a bad surprise.

And from experience, that kind of surprises always come when you least need them.
