Delegating issue

[Chris Buxton]

It can't be done, neither with a CNAME record nor with delegation.  
The server that handles the test.com zone must know the answer for  
the address of test.com.

The best you can do is to set up a separate web server (or virtual  
host) for test.com that redirects all such requests to www.test.com.

If web browsers supported SRV records, I could give you a better  
answer, but they don't.
