I'm not sure what the problem is.  The db file should look like:

main IN A 10.0.0.1
sub1 IN A 172.16.1.1
sub2 IN A 192.168.1.1

If you also want to be able to refer to all the addresses using a single
name, add:

common IN A 10.0.0.1
       IN A 172.16.1.1
       IN A 192.168.1.1

The reverse domains for the subnets should probably just contain the unique
names, not the shared name.
