A DNAME record is used to create an alias for an existing DNS name. It provides redirection from part of a DNS name to part of the DNS name through an alias. It also provides mapping of sub-domains. For example, for the website infoblox.com, you can create a DNAME infobloxcorporate.com. If a sub-domain is created as sales.infoblox.com, the sub-domain will be automatically created as sales.infobloxcorporate.com. Here, the DNAME record is infobloxcorporate.

To create a DNAME Record, complete the following:

From the Infoblox Portal, click Configure > Networking > DNS > Zones.
Click the DNS view.
Click the zone.
Click Create > Record and select DNAME Record from the drop-down list.

On the Create DNAME Record page, specify the following and click Save & Close:

Alias: Specify an alias for the record. If you are adding a DNAME record for the entire zone, leave this field empty. This field is for adding a DNAME record for a subdomain within the selected zone.

Target: Enter the domain name to which you want to map all the domain names specified in the Alias field.
Description: Enter a descriptive comment about the Generic Record.
