title: DNS Gurus: How to forward www.domain.com to domain.com using DNS only?
body: <p>I am running a blog at posterous.com, and they can host my domain name if I create an A record to their IP in my domain registrar's custom DNS tool.</p>
  
  <p>The problem is that I want my domain to ALWAYS read domain.com, so I want to have my DNS remap any requests to www.domain.com to domain.com, and I can't use .htaccess or PHP or other server methods, since it's just a blog interface.</p>
  
  <p>So far, I've tried:</p>
  
  <pre>
  @ A target.ip.address
  www CNAME domain.com
  </pre>
  
  <p>Which redirects www.domain.com to the right site, but the www. is still on the domain. I heard you could do:</p>
  
  <pre>
  @ A target.ip.address
  www A internal.redirector.ip.address
  </pre>
  
  <p>but I don't know my registrar's internal IP address that might handle this redirection (or even if such a thing actually exists).</p>
  
  <p>Can what I'm asking for be done?</p>
  
  <p>Thanks, you guys rock.</p>
