CNAME record, aka alias record, allows you to map multiple names to the same computer and is generally used for computers providing both www and mail services.

Verifying the Effectiveness of a CNAME Record

The time for a CNAME record to take effect varies by DNS service provider. It is generally within half an hour. You can also check whether the CNAME record is in effect in the following ways:

• Method 1: Click Start → Run → enter cmd, press Enter, and enter the PING command to check whether the CNAME is effective. If the resolution result returned is the same as the CNAME of the domain name, the CNAME configuration is effective.
• Method 2: Click Start → Run → enter cmd, press Enter, and enter the nslookup command to check whether the CNAME is effective. If the resolution result returned is the same as the CNAME of the domain name, the CNAME configuration is effective.
