DNS Subdomain Vs Delegation

In a production environment you would simply create a
subdomain without delegation. The only exception that I
have ever seen, one that Microsoft implemented in Server
2003, is the automatic local delegation of the _MSDCS
namespace. They did that because there was a problem when
domain controllers in other domains in a forest would try
to get updates about all the domain controllers in the
forest using the server type or by GUID.
Check out this link for some additional detail on DNS,
delegation, and secondary zones in Windows Server 2003
