Is there anything I have to enable on my side to query these "double CNAMEs"?
dig @8.8.8.8 cdn2.example.com
cdn2.example.com 3600 IN CNAME cdn2.example2.com
cdn2.example2.com 3600 IN CNAME cdn3.example2.com
cdn3.example2.com 3600 IN A 1.2.3.4
Thanks a lot guys,

Folks,
When I try to get an IP address for some sub-site/domain, let's say
cdn2.example.com --- I'm getting errors, BUT when I query
Google's DNS servers I'm getting an IP address:
dig @8.8.8.8 cdn2.example.com
cdn2.example.com 3600 IN CNAME cdn2.example2.com
cdn2.example2.com 3600 IN CNAME cdn3.example2.com
cdn3.example2.com 3600 IN A 1.2.3.4
This is my DNS configurations/errors:
