Different domains, or different addresses/Web sites? The latter
is certainly possible, but the former is a meaning noise since
'.' is a delimiter, not part of a domain name itself.

The second statement is accurate. Consider the following
snippets from hypothetical DNS zone files:

@ IN SOA Zardoz.CC. (...)
@ IN A

In this case, both <> and <>
will give you the same Web server system (though the actual Web
sites may be different depending upon the server's configuration).

@ IN SOA Zardoz.CC. (...)
@ IN A

In this case, the two requests resolve to two different IP addresses.
What Web server [virtual] host fields each depends upon the
configuration of the system(s) with those addresses. It
might be a single multihomed system with both names identified
in ServerName/ServerAlias directives as applying to the same
virtual host.. or not.
