A CNAME record or canonical name record makes one domain name an alias of another. The aliased domain gets all the subdomains and DNS records of the original. Aliases allow a single host computer to appear to be multiple host computers. For example, the host gamma.tvpress.com can be made to appear as www.tvpress.com and ftp.tvpress.com.
To add a CNAME DNS record, perform the following operations:
- Choose All Domains from the Subscription selector at the top of the control panel screen. The list of your domains opens.
- Click on the name of the domain you wish to add DNS record to. The Summary tab of the domain will open.
- Move to the DNS tab. Select the DNS Records sub-tab. The list of all DNS records will appear.
- Click on the Add New DNS Record button to add a new DNS record.
- On the displayed page, select the CNAME DNS record type and then specify the following DNS record properties:
- In the Domain field enter the alias domain name for which you wish to create the CNAME record.
Note: You can use the underscore symbol
_
in a domain field of CNAME records. - Into the Canonical name field type the domain name within which you wish the alias to reside. Any domain name can be entered. It does not need to reside on the same server.
- TTL: (short for Time-To-Live) set how many seconds will elapse before the record is refreshed in the DNS cache. It is expressed in seconds.
- In the Domain field enter the alias domain name for which you wish to create the CNAME record.
- Click on the Finish button to complete the adding of the address DNS record.
Note: There must always be an A record for the machine before a CNAME record (aliases) can be created.
Important: If the operation cannot be performed and the error message is shown like DNS Record data matches some of restriction rules. Creation is prohibited.
, it means the your hosting provider restricts you from adding certain "CNAME" records. To resolve the issue, you should contact your hosting provider.
