What Is Azure DNS Name Server?


Angela Bailey

Azure DNS is a cloud-based domain name system (DNS) service provided by Microsoft Azure. It allows you to host and manage your domain names using Microsoft’s global network of DNS servers. With Azure DNS, you can easily map your domain names to Azure resources such as virtual machines, web apps, and storage accounts.

Why Use Azure DNS Name Server?

There are several compelling reasons to use Azure DNS as your name server:

  • Reliability: Azure DNS is built on the same infrastructure that powers Microsoft’s own DNS services. This ensures high availability and reliability for your domain names.
  • Scalability: With Azure DNS, you can easily handle large amounts of traffic and scale your domains as needed.
  • Integration: Since Azure DNS is part of the Azure platform, it seamlessly integrates with other Azure services. You can manage your DNS records alongside your other resources.
  • Global Reach: Microsoft operates a worldwide network of data centers, ensuring fast and reliable resolution for users around the globe.

Getting Started with Azure DNS

To start using Azure DNS, you need an active Microsoft Azure subscription. Once you have that set up, follow these steps:

  1. Create a DNS Zone:
  2. The first step is to create a new DNS zone in the Azure portal. A DNS zone represents a domain name that you own or control. Specify the name of the zone (e.g., example.com) and choose the resource group where it will be located.

  3. Add Records:
  4. After creating the zone, add records to define the mappings between your domain names and the corresponding IP addresses.

    Azure DNS supports various record types, including A, CNAME, MX, and TXT.

  5. Delegate Your Domain:
  6. To start using Azure DNS for your domain, you need to update the name server records with your domain registrar. This delegates the management of your domain’s DNS to Azure DNS.

  7. Verify Configuration:
  8. After delegating your domain to Azure DNS, verify that the configuration is correct. You can use tools like nslookup or dig to query the name servers assigned by Azure DNS and ensure they return the expected results.

Managing Azure DNS

Azure provides a user-friendly management interface for working with your DNS zones. In addition to using the Azure portal, you can also manage your domains programmatically using Azure PowerShell or the Azure CLI.

Azure Portal:

The Azure portal offers a graphical interface for managing your DNS zones. You can add or remove records, modify existing records, and monitor the health and performance of your domains.

Azure PowerShell:

If you prefer working from a command-line interface (CLI), you can use Azure PowerShell to manage your DNS zones. PowerShell provides powerful scripting capabilities for automating common tasks.

Azure CLI:

Similar to PowerShell, the Azure CLI allows you to manage your DNS zones using command-line tools. It is cross-platform and works on Windows, macOS, and Linux systems.


Azure DNS Name Server is a powerful service that simplifies the management of your domain names in Microsoft Azure. With its reliability, scalability, integration capabilities, and global reach, it is an ideal choice for hosting and managing your DNS records. By following the steps outlined in this article, you can get started with Azure DNS and take advantage of its many features.
