Assume the customer domain name is sampledomain.com, and that they have control over (are primary for) sampledomain.com. Also assume that the customer has been assigned 204.71.1.0/27 as their fractional class C network.
The fractional class C template would be:
[in-addr-cname.template.960313]
action: N
network/prefix-length: 204.71.1.0/27
domain name suffix: sampledomain.com
billing ID: 12345678

The records that will be added to the SKY Internet name server are:
0.1.71.204.in-addr.arpa. IN CNAME 204.71.1.0.sampledomain.com. 1.1.71.204.in-addr.arpa. IN CNAME 204.71.1.1.sampledomain.com. [...] 31.1.71.204.in-addr.arpa. IN CNAME 204.71.1.31.sampledomain.com.
In the primary name server for sampledomain.com you would add PTR records, such as:
204.71.1.0.sampledomain.com. IN PTR hostname.sampledomain.com.
You would substitute the actual host names of the systems instead of hostname.sampledomain.com above.
A sample query would then look like:
host -t ptr 1.1.71.204.in-addr.arpa 1.1.71.204.in-addr.arpa CNAME 204.71.1.1.sampledomain.com 204.71.1.1.sampledomain.com PTR hostname1.sampledomain.com
