What is Azure DNS?

The Domain Name System (DNS) locates and translates website domain names into internet protocol (IP). The Azure DNS provides name resolution for DNS domains by using Microsoft Azure infrastructure. It provides hosting of your Azure DNS names on the Azure global network of DNS name servers. The Azure DNS system uses Anycast networking for fast performance and high availability for your domain. Each DNS query is answered by the closest available DNS server. 

You also get benefits specific to Azure Resource Manager such as role-based access control, audit logs, and resource locking. It also allows you to manage domains and records via the Azure portal, Azure PowerShell cmdlets, and the cross-platform Azure CLI. You can also integrate your Applications that require automatic DNS management via the REST API and SDKs.
