Checking Whether the CNAME Record Has Taken Effect

The length of time before the CNAME record takes effect depends on the DNS provider. To check whether a CNAME record has taken effect:

Open the command line interface that comes with Windows and run the following command:

nslookup -qt=cname Acceleration domain name

If the CNAME is displayed, the CNAME record has taken effect.

If the CNAME record has taken effect, your domain name has been successfully connected to CDN for acceleration.
