Canonical Name (CNAME) records allow you to create alias names that correspond to existing Internet host records. CNAME records are helpful when pointing multiple domain names to the same host.
For example, the company Jim's Bikes, at www.jimsbikes.com, creates the host name europe.jimsbikes.com for its European factory. The company wants to market specific branded addresses such as scotland.jimsbikes.com, ireland.jimsbikes.com, and greatbritain.jimsbikes.com. The company can easily create new names for the same host by creating CNAME records for Scotland, Ireland, and Great Britain to the alias Europe.
When creating aliases:
- Be careful in using CNAME records because only users highly familiar with DNS should attempt to use CNAMES. For example, you could create routing problems for all of your DNS information, including your website and e-mail.
- Understand that DNS updates will take up to 2 hours to take effect (updates may resolve more quickly at some locations than others because many name servers on the Internet retrieve updates at different times).
To update CNAME records
- Follow instructions for accessing DNS Manager – Advanced Tools to view the DNS Manager Settings page.
- On the DNS Manager Settings page, in the Host Aliases: CNAME Records section, click Add/Edit.
- Your current CNAME records are listed in editable form, and any Network Solutions service that is associated with the CNAME record is listed under the Other Host text box.
- To add/edit CNAME records:
- Enter or edit the alias name in the Alias text box.
- Select one of the two options, Refers to Host Name or Other Host.
- If you selected Refers to Host Name, select the host name from the drop-down box under the Host Name column.

- Click Continue.
