Creating a CNAME record - Canonical Name
CNAME is technically an alias for a different URL. You don't have to use it, you can just use the CDN URL for the CDN Integration. If you wish to set a CNAME for your stream, here are the instructions on how to set it.
First, you have to specify the CNAME in the CDN77 Control Panel. Please log in to the Control Panel and select your Streaming Channel for which you wish to add the CNAME. Then in the CNAMES & SSL section, you should add your CNAME by clicking at the Add CNAMES button. Once this is done, you will have to add the CNAME record in your DNS.
In the Overview section of the Streaming Channel, you can see the URL, labeled as "CDN Resource URL:". You will need that in order to add the CNAME record in your DNS settings.
To add the CNAME in your DNS, log into your domain name control panel provided by your hosting and find the editing area for your DNS settings.
If you’re not sure how to do this, contact a representative from your hosting provider. They’ll be able to supply you with instructions on how to add the record or maybe make the step for you. Depending on your domain name provider it may take up to 24 hours for the DNS changes to fully propagate once they’ve been made.
You can add up to 10 CNAMES to one CDN Resource. If you would need more, please contact us at firstname.lastname@example.org
Confirming that your CNAME has been installed
The following instructions are for the exemplary case where you would set your CNAME to cdn.yourdomain.com.
In a Unix System:
You can check your CNAME status by using the Linux command dig +trace cdn.yourdomain.com
You should see something similar to the example below:
In a Windows System:
Click on your Windows start button and type "cmd" in the box. A DOS window will open up. Type the command nslookup cdn.yourdomain.com
