How to create a Cname record in DNS registry for Cdn service for app on bluemix

I am trying to add a cdn service to my Bluemix app. So before using the service, I need to configure the routes, which I did. I am using a trial version, so my app domain will be the normal Bluemix default, i.e. mybluemix.net. When I add the app url and the origin route to the cdn service domains tab, it displays the cname and states

CName for app improperly configured to ERROR:Resolver get NoAnswer.

Documentation for the cdn service says:

"Replace the CNAME target for your domain in your DNS provider record with the CNAME displayed".

I don't understand this, because my domain is the default trial one provided by Bluemix, i.e. mybluemix.net. So is there any way that I can view the DNS provider and update the Cname? Help me out if you have any idea. Need Help. Thanks!!

So your current domain without CDN may look like this (take www.stateless.co for example):

dig www.stateless.co +short
79.170.40.170

It is pointing to a A record in DNS.

So when you start to use CDN, you will need to do configuration in your CDN provider. After the configuration, you will be provided with a CDN hostname to which you need to point your domain as CNAME (you do it in your DNS service provider side). An existing example:

dig www.akamai.com +short
www.akamai.com.edgekey.net.
www.akamai.com.edgekey.net.globalredir.akadns.net.
e1699.dscc.akamaiedge.net.
104.69.150.163

where www.akamai.com is pointing to CNAME www.akamai.com.edgekey.net (www.akamai.com.edgekey.net is the CDN hostname provided by Akamai as a CDN provider). Below are the details:

dig www.akamai.com 

; <<>> DiG 9.8.3-P1 <<>> www.akamai.com
