Recipe for Success:

1. Design your DNS namespace as if your network is intimately connected to the 
Internet.

2. Use internal subdomains for general end systems if needed.

3. Don’t serve the zones for internal subdomains to the Internet at large.

4. Keep in mind that DNS resolution .ne. reachability.

5. Last, but not least, expect policy change from your management about 
connectivity. Ingredient 1 is key here.
