<p><font size="3" face="Times New Roman"><span style="font-size:12.0pt">Either is fine. Using the cname would require a single update if your ip changes, but prevents other records at the same level. So you couldn't attach mx for instance at
<a href="http://example.com">example.com</a> and <a href="http://www.example.com">
www.example.com</a> if you wanted to.<o:p></o:p></span></font></p>
