Create a separate zone for each hostname on your local net:

zone "machine1.company.com" {
  type master;
  filename "db.machine1";
};
zone "machine2.company.com" {
  type master;
  filename "db.machine2";
};
and so on.

Your local DNS server will use the regular DNS lookup process to find
anything in the rest of the company.com domain.
