Geographic mapping lets you configure a property that returns a CNAME based on the geographic location of the request. You can reuse maps for multiple properties or create new ones. The minimum number of map definitions is two so that:
- At least one maps one or more countries to a data center.
- One routes all other traffic
A geographic zoning map lets you split the world into several geographic zones. Properties that use the map can specify a handout CNAME for each zone on the property's editing page.
