I think it's pretty obvious what he's trying to accomplish -- it's an 
extremely common situation.  His web site has a dynamically assigned 
address, and he wants users to be able to access it as either 
www.<domain> or just <domain>.  He uses a domain like dyndns.org to 
provide a static name that always maps to the address, but he doesn't 
want end users to have to use that name.

For the www name, he can use an alias:

www CNAME whatever.dyndns.org.

but there's no similar solution for the bare domain.

What many people do to solve this problem is find a third party that 
will implement a simple HTTP redirector for http://<domain>, to redirect 
it to http://www.<domain>.
