Adding Record Sets for a Private Zone

An A record maps a domain name to the private IP address of an internal server or device.

Constraints

An A record cannot coexist with a CNAME record for the same name.

For details about the conflict rules and handling measures, see Rules for Handling Record Set Conflicts.

Procedure

1. Go to the Private Zones page.
2. Locate the target zone and click Manage Record Sets in the Operation column.

   

3. Click Add Record Set above the record set list.

   

4. On the Add Record Set page, set record set parameters as instructed.

For example, if the domain name is example.com, the value of the Name can be as follows: www: The domain name is www.example.com and usually used for a website. Left blank: The domain name is example.com and usually used for a website. To use an at sign (@) as the domain name prefix, just leave this parameter blank. abc: The domain name is abc.example.com, a subdomain of example.com. mail: The domain name is mail.example.com and usually used for email servers. *: The domain name is *.example.com. It covers all subdomains of example.com.	Leave it blank.

A CNAME record maps a domain name to another. CNAME records can simplify private zone management. For example, if www.internal is mapped to webserver.internal, you only need to modify the A record when the IP address of webserver.internal changes.

Constraints

A CNAME record cannot coexist with other types of records for the same name.
