How to Add CNAME to a DNS
A CNAME record is needed when you are redirecting your domain to another site, such as a blog that is hosted on a blogging platform or a social media network page or profile. It is also used for third-party email services. Adding a CNAME (canonical name) record to a DNS zone is done by accessing your domain registry control panel and adding the necessary information where prompted to do so. Most domain registry control panels are set up for easy addition of a CNAME record, and all that is necessary is administrator access to your control panel.
Things You'll Need
- Administrator access to your domain registry control panel
Log into your domain registry control panel with your administrator login and password.
Unlock your DNS records. Your hosting control panel has either a lock and unlock prompt or an icon which you click on to unlock your records.
Open your settings profile and locate the CNAME entry field. It is usually empty and appears next to or above the legend "CNAME".
Enter the CNAME record which is provided to you by the platform that is hosting your actual content.
Enter an alias in the "HOST" field which is associated with the "CNAME" field (usually located to its left ) if necessary. This alias is necessary if you want an address on your domain other than your main address to point to your files. It is also necessary if you are changing the CNAME record for your mail server rather than your entire domain. For example, if your domain is mydomain.com and you want to point blog.mydomain.com to a blogger platform, you would enter "blog" in the "HOST" field. In the case of mail servers, the alias is "mail."
Save your changes. Relock your domain. It will take up to 48 hours for your CNAME record to propagate across the Internet. Keep checking your domain or your new mail host to see if the changes have taken effect. If they have not taken effect within 72 hours, contact your domain registry technical support department.
