Do you get that /56 from starlink or from somebody else?
If you use a non-starlink router, it might be that the IPv6 feature of
that non-starlink router gets that /56 from the outside of starlink domain.

Ok, good to know.

Yes, it might be indeed that the router (provided by starlink router, or
not by somebody else) runs a DHCPv6-PD server.
