I should add that you need those also for subdomains leading up to
f.e.e.b and d.a.e.d:

$ORIGIN 4.c.f.f.8.d.6.1.1.0.0.2.ip6.arpa.
*				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.b				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.e.b				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.e.e.b				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.d				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.e.d				IN	PTR	out-of-bounds.ipv6.cmd.nu.
*.a.e.d				IN	PTR	out-of-bounds.ipv6.cmd.nu.

If you want to worry about all the little subdomains, then you need to
add the following:

$ORIGIN 4.c.f.f.8.d.6.1.1.0.0.2.ip6.arpa.

b				IN	PTR	out-of-bounds.ipv6.cmd.nu.
d				IN	PTR	out-of-bounds.ipv6.cmd.nu.

$ORIGIN f.e.e.b.4.c.f.f.8.d.6.1.1.0.0.2.ip6.arpa.

0				IN	PTR	not-active.ipv6.cmd.nu.
2				IN	PTR	not-active.ipv6.cmd.nu.
0.0				IN	PTR	not-active.ipv6.cmd.nu.
2.0				IN	PTR	not-active.ipv6.cmd.nu.
e.2				IN	PTR	not-active.ipv6.cmd.nu.
...

$ORIGIN d.a.e.d.4.c.f.f.8.d.6.1.1.0.0.2.ip6.arpa.

0				IN	PTR	tunnel.ipv6.cmd.nu.
0.0				IN	PTR	tunnel.ipv6.cmd.nu.
...
