Create Azure DNS zones
Azure DNS provides a reliable, secure DNS service to manage and resolve domain names in a virtual network without needing to add a custom DNS solution.
An Azure DNS zone hosts the DNS records for a domain. To begin hosting your domain in Azure DNS, you need to create a DNS zone for your domain name. Each DNS record for your domain is then created inside your DNS zone.
Things to know about DNS zones
You can add a DNS zone in the Azure portal, as shown in the following image. Several configuration settings are required to create a DNS zone. In the portal, you specify the DNS zone name, number of records, resource group, zone location, associated subscription, and DNS name servers.
Take a moment to review some important characteristics about DNS zones.
Within a resource group, the name of a DNS zone must be unique.
By providing a unique name when you create a new DNS zone, Azure ensures that the DNS zone doesn't already exist in the resource group.
Multiple DNS zones can have the same name, but the DNS zones must exist in different resource groups or in different Azure subscriptions.
When multiple DNS zones share the same name, each DNS zone instance is assigned to a different DNS name server address.
The Root/Parent domain is registered at the registrar and then pointed to Azure DNS.
Child domains are registered directly in Azure DNS.
Tip
You don't have to own a domain name to create a DNS zone with that domain name in Azure DNS. However, you do need to own the domain to configure the domain.
