I understood that, now, I have another issue. The main domain the is used in the zone (
zone "example.com" ) don't resolve to anything and I want it to be resolved
from 8.8.8.8, while the sub-domains still resolve from my DNS as specified in the zone
record file.
than you need the subdomains in own zone-files and don't delegate them
in the public view
BTW: stop talking about "be resolved from 8.8.8.8" when the terminology
is private and public views

I have a main domain ( aa.example.com) with hunderds of subdomains ( bb.aa.example.com).
I made a wildcard record to forward all subdomains (bb.) to a list of addresses in
round-robin fashion. The problem I am fscing is the wildcard is forwarding anything
towards the the IP ( example , "cc.bb." which is not a vaild subdomain). How
can I limit that so it will only forwards ( bb.aa.example.com) and drops any invalid
subdomains ( cc.bb.aa.example.com ).
Note: aa, bb, and cc being any arbitary value.
With a standard BIND zone, you can't. Wildcards match multiple labels. That
goes to the earliest days of the DNS,

You'd need a specialized handler to do this.
