Handout CNAMEs

In a property's configuration, you can optionally enter a handout CNAME for each data center. When you make a query for such a property, GTM determines to which data center you should be mapped. If that data center has a handout CNAME configured, the answer returned is the handout CNAME, rather than the servers that might be configured for the data center.

Handout CNAMEs are most often used with autonomous system (AS) maps, CIDR maps, and geographically mapped properties, but they can be used with any type of property.
