Set-AzureService for making reverse DNS

When I run
PS C:\> Set-AzureService -ServiceName "TheNameofMyservice" -Description "App with Reverse DNS" -ReverseDnsFqdn ""

I get this:

Set-AzureService : BadRequest: The reverse DNS FQDN must resolve to one of:

a). the DNS name of this Hosted Service (,
b). the DNS name of a different Hosted Service in this subscription (xxxxxx-xxxxx-4xa1-2aa-ce91e4316997),
c). a Reserved IP belonging to this subscription,or
d). the IP of a deployment or of a VM in this subscription.

Error merely says you use a reverse name that is not associated with your azure subscription. You need to enter it somewhere in your subscription like a site name etc before using as reverse name.
