This article covers:
What is a CNAME Record?
Canonical Name (CNAME) records are a type of Advanced DNS record that point a domain or subdomain to a server name. Unlike Address (A) Records, CNAME Records do not point to an IP address.
This is the name of the record, which can also be called the "Host". Your domain name will automatically be appended to the end (example: if you enter "www" the record will change to "www.rebelexample.com" when saved).
Value (Points To)
This is the server name to which the CNAME record will point.
TTL (Time To Live)
The TTL sets the amount of time in seconds for the record to stay cached before retrieving it again. The default TTL is 3600, which is approximately one hour. Lowering the TTL of a new record will not decrease the amount of time it takes for the record to update.
How do I edit/add my CNAME Records?
|Note: Any changes that you make to your Advanced DNS settings can interrupt your service. If you are not an advanced user, we strongly recommend that you not change these settings without consulting our support department.|
Login to your Rebel account and click Domain Manager.
Click directly on your domain name to access the domain editing page.
On the domain editing page, select the DNS tab. Scroll down to Manage Advanced DNS Records and click on New Advanced DNS Manager.
|Note: If the Nameserver Information section shows your domain as set to Use Third Party Hosting, the Advanced DNS will only be accessible with your hosting provider. Advanced DNS records live on nameservers. You will only be able to access the Advanced DNS from within your Rebel account if the name server information for your domain is currently set to Park with Rebel, Forward Domain, or Host with Rebel.|
To add a CNAME record, click the button to Add New Record and set the Record Type as CNAME. Fill in the Alias and Points To fields as instructed by your hosting service provider. You can leave the TTL as it is. Click the green button to Save.
To edit an existing CNAME record, click the Edit button update the Alias and/or Points To fields, as instructed by your hosting service provider. You can leave the TTL as it is. Click the green button to Save.
|Note: When editing the Advanced DNS for a domain that is already set to Park with Rebel, Forward Domain, or Host with Rebel, the propagation time will be approximately 1-2 hours. If your domain was previously pointed to third party nameservers, updates can take up to 24-48 hours to propagate worldwide, though we find it's typically much closer to 6-12 hours.|
My email stopped working!
If your CNAME record alias is a root domain (such as rebelexample.com, rather than www.rebelexample.com or shop.rebelexample.com) it will block your Mail Exchanger (MX) record, and any other root domain records. Your CNAME records should not be a root domain.
