I need to create the CNAME record: =

but my DNS provider ( only allows me to create it at the sub-domain level (i.e. I have confirmed with the technical support that the cannot create a CNAME at the sub-sub-domain level (i.e.

Is there a way I can create a sub-sub-domain level (i.e. CNAME record by referencing DNS names? If not, what is the best solution?

Your question lacks technical rigor, probably due to a lack of knowledge about how DNS works, so I am going to assume you mean the following:

  • you own domain, which is registered at, who also provide you with name services for this domain.
  • you wish to create a DNS entry called, and point this at something
  • your registrar/hosting provider says they cannot oblige

If this is correct, get a better hosting provider;, for example, is free and allows you to do anything that is valid in a DNS zone.

Sorry if I wasn't clear. I do understand DNS, but I thought sub-sub-domain would be a clearer term as I've seen other people use that :-) Thanks for the info. – Techboy Oct 27 '11 at 10:54
+1 yes, get a better DNS host. – Alnitak Oct 27 '11 at 13:25

By sub-sub domain I assume you mean And by not supporting it I assume you mean their DNS management system doesn't allow you to add x.y as a CNAME record.

I think you will need to switch domain providers, or use a different nameserver, since Azure will surely be looking at the authoratitive name server for authentication.

Are you sure that Azure require you to register a sub-sub domain for authentication?

'Are you sure that Azure require you to register a sub-sub domain for authentication?'. It's what they are asking for in their Management Portal, but I could e-mail them to see if there is another method. Thanks. – Techboy Oct 27 '11 at 10:56
It would be helpful if you gave an example of what they are actually asking for - obfuscated if you are paranoid about sharing your domain name on this forum :-) – dunxd Oct 27 '11 at 10:58
