In fact it Should not.

No.  That would be Bad.  You Must use some other namespace.  That's why I 
suggested ".local".

Multiple domain parts separated by periods.  Each domain part is a string 
consisting of letters, numbers, or hyphens.

The domain name is separate from the machine name.  I have funknet.net 
registered, so I can use whatever names I want within that.  In DNS, 
www.funknet.net points to one server, www2.funknet.net points to another, 
and mail.funknet.net points to another.
And in my private network I can use whatever funknet.net names I want that 
don't conflict with the others I've set.

Depends on the meaning of "like" there.

In my home network I use the subdomain local.funknet.net, so for example 
right now I'm using the machine hactar.local.funknet.net.

Servers are different from domains.  Servers are given names within 
domains.  A domain can contain many servers.  (I have another machine at 
home called marvin.local.funknet.net.)

Of course, a single server can also answer to multiple names or even 
multiple domains, but that's a story for another time.
