Reverse DNS on a /27 delegation and zone files

[Alex]

Hi,

To follow up with my own email, I found a mistake that I made have corrected it.

It seems I do need to provide PTR records. I confused the CNAMEs that
my provider creates with the PTRs that I create.

I'd still be interested in knowing:

> zone "0/27.yy.3.64.in-addr.arpa" {

Was there a change between 9.4.2 and the current that provided the
ability to use the hypens versus the slash as a subnet separator?

Does anyone know if this format is documented well in O'Reilly's
DNS&BIND v5? Do you know up to what specific version it's applicable,
or perhaps even it's current?

Thanks again,
Alex
