How do I make a CNAME record?

Overview

CNAME (or Canonical) records are used to resolve to another hostname rather than an IP address (as A records do). They may be used when pointing a domain to a service such as Blogger, Tumblr or Gmail, where user accounts are subdomains or directories of the service.

Example:
 

Name

TTL

Record Class

Record Type

Host

blog

3600

IN

CNAME

ghs.google.com


In this example, whenever a request is made for the URL: http://blog.mydomainname.com.au, the CNAME record will direct visitors to Google's Blogger servers at ghs.google.com. If a Blogger user has set up a blog at Blogger such as http://mydomainname.blogspot.com but wants to use a custom domain name, they'll need to configure the Blogger servers to accept the blog.mydomainname.com.au name request as well as point the hostname blog.mydomainname.com.au to the Blogger servers via the CNAME record.

Changing CNAME records

To modify or create any CNAME records
  1. Login to your Account level console
  2. Manage the domain you want to make changes to
  3. Click Zone Manager in the left column (Note: If this option is not displayed, please contact TPP Wholesale Technical Support. The Zone Manager page details the domain zone records and allows for changes to A, CNAME, MX, NS, TXT  or SRV records)
  4. Select CNAME in drop down menu and click 'Create New Record' 
  5. In the following page, fill in the blank fields: 
  • Name - Type in the subdomain you wish to create a CNAME record for.eg. Type blog,mail, or www rather than the full hostname such as blog.mydomainname.com.au or www.mydomainname.com.au
  • TTL - This is the Time to Live, it is best to leave the default setting
  • Host - The name of the host to point the subdomain to, such as ghs.google.com
  1. Click [Add Record]
Note: Standard DNS propagation time of up to two hours may apply. Refreshing the internet browser's cache can help to display the changes if they're not automatically visible after two hours. Press CTRL-F5 (PC) or CMD-R (Mac).
