It isn't, because a customer gets /48 or /56 in most cases. The
customer's router can use various methods to assign addresses, auto
configuration and DHCPv6. If the ISP wants to provide reverse zone for
all possible addresses (ISP doesn't know which one of the assigned are
used by the customer), it must have all reverse zones on their zone
file or dynamically create them when a DNS server receives a request.
