Hello Peter,<br><br>Google and amazon use CNAME's instead of A to point to their webservers. Some example: <a href="http://blog.cloudflare.com/zone-apex-naked-domain-root-domain-cname-supp#%21/">http://blog.cloudflare.com/zone-apex-naked-domain-root-domain-cname-supp#!/</a><br>
<br>Amazon and Google have the right to modify the IP of their CNAME so if you use an A record to make <a href="http://example.com">http://example.com</a> working and their modify the IP then <a href="http://example.com">http://example.com</a> isn't working anymore.<br>
<br>I'll get more and more requests from customers that asked me to create an "apex cname" for there domains. Apex CNAME's in combination with Microsoft DNS works correctly (even the RFC isn't support this officially). Apex CNAME's in PowerDNS also works but the MX are broken after the change.<br>
<br>Is there any other way with PowerDNS to workaround this? <br><br>PS. I found the RFC about this issue: <a href="http://www.faqs.org/rfcs/rfc1912.html">http://www.faqs.org/rfcs/rfc1912.html</a><br><br>Regards,<br>Thomas<br>

<br>
</div>I have never seen Google and Amazon do anything with apex CNAMEs (what you call empty CNAMEs). Do you have any examples?<br>
<br>
Kind regards,<br>
