How can I create a sub sub domain to the Azure cloudapp.net domain?

Question

I have a sub domain assigned from Azure:

sub.cloudapp.net

I want a sub sub domain:

sub.sub.cloudapp.net

I have tried to create a DNS zone in Azure portal and added a CNAME:

sub.sub.cloudapp.net -> sub.cloudapp.net

When I check "$ host" using the azure dns server I get:

Using domain server: Name: ns1-05.azure-dns.com Address: xx.xx.x.x#53 Aliases:

sub.sub.cloudapp.net is an alias for sub.cloudapp.net.

When I check regular "$ host" without using the dns server I get (after 1 hour DNS propagation time):

Host sub.sub.cloudapp.net not found: 3(NXDOMAIN)

I this the correct way to do it? Or should I wait more for the propagation?

Looks like second-level subdomain is not supported, check out here: Second Level Subdomains in Azure Apps
