Deligate entire block using new RFC2317 syntax to reduce entry

[SingSong]

I'm running named(9) ver 9.2.1, and the reverse DNS is not working using
below.  Please help, thanks.

$origin cc.bb.aa.in-addr.arpa.
$generate 1-2 0 NS ns$.abc.com.           ; ns1 + ns2
$generate 1-255 $ CNAME $.0             ; IP1 thru IP 255
