What is a CNAME?

The CNAME record is a DNS record which points a domain name to another domain name, rather than to an IP address.

Please note that you cannot use CNAME to point to a sub-directory, specific file, or URL, but only to a domain and or a subdomain.

So for example, you can use CNAME to point www.your-domain.com to:

• new-domain.com
• www.new-domain.com
• your.new-domain.com

But you can’t use CNAME to point www.your-domain.com to:

• new-domain.com/yourdomain.html
• new-domain.com/yourdomain/

To change the CNAME:

1. Log into your Domain Control Panel for your domain
2. Click ‘DNS Management’
3. Under ‘Create New A/AAAA/CNAME records’:

1. 1. In ‘Subdomain’, enter:

www

1. 2. In ‘Address’, enter:

www.new-domain.com.

Please note the full stop at the end of the domain name.  That must be added.

4. Click ‘Update DNS’
5. Your CNAME will be changed

Please allow 48 hours for the DNS change to be propagated across the Internet.
