Google provides no Service-Level agreements (SLA) or technical support commitments for Preview features. For more information, see GDC's [feature stages](/distributed-cloud/hosted/docs/latest/gdch/resources/feature-stages).\n\nThis page explains how to prepare your Identity and Access Management (IAM) permissions to effectively use Cloud DNS within GDC.\n\nGDC offers IAM for granular access to specific GDC resources and prevents\nunwanted access to other resources. IAM operates on the security principle of\nleast privilege and controls who can access given resources using IAM roles and\npermissions.\n\nA role is a collection of specific permissions mapped to certain actions on\nresources and assigned to individual subjects, such as users, groups of users,\nor service accounts. Therefore, you must have the proper IAM roles and\npermissions to use managed DNS services in GDC.\n\nThe intended audience for this page is platform administrators and application\noperators responsible for network administration and managing DNS for their\norganization within GDC.\n\nGet IAM permissions\n-------------------\n\nTo create DNS zones and records, you must have the necessary identity and access\nroles. Ask your Project IAM Admin to grant you the roles:\n\n- Managed DNS Project Viewer (`managed-dns-project-viewer`) role: creates and updates DNS zones and records.\n- Managed DNS Project Admin (`managed-dns-project-admin`) role: views existing DNS zones and records.\n\nFor more information on these roles, see\n[Role definitions](/distributed-cloud/hosted/docs/latest/gdch/application/ao-user/iam/role-definitions).\n\nWhat's next\n-----------\n\n- [Create DNS zones](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/dns/create-dns-zone)\n- [Create DNS records](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/dns/create-dns-records)"]]
