Defining delegated route /48 from Hurricane Electric in Appropriate way.

I’ve been thinking on how to create reverse zone for /64 subnet from delegated routed /48 from Hurricane Electric. First when i was first time request delegation for routed /48 i’ve defined this configuration on my nameservers

In named.conf

zone "7.e.8.f.0.7.4.0.1.0.0.2.ip6.arpa" {
type master;
file "reverse-2001-470-f8e7_48.IP6.ARPA";
};
