# CreateDNSView
<a name="API_route53globalresolver_CreateDNSView"></a>

Creates a DNS view within a Route 53 Global Resolver. A DNS view models end users, user groups, networks, and devices, and serves as a parent resource that holds configurations controlling access, authorization, DNS firewall rules, and forwarding rules.

**Important**  
Route 53 Global Resolver is a global service that supports resolvers in multiple Amazon Web Services Regions but you must specify the US East (Ohio) Region to create, update, or otherwise work with Route 53 Global Resolver resources. That is, for example, specify `--region us-east-2` on Amazon CLI commands.
