What Is Azure DNS Server?


Larry Thompson

Azure DNS is a cloud-based Domain Name System (DNS) service provided by Microsoft Azure. It allows you to host your domain names in Azure and manage DNS records using a simple and easy-to-use interface. With Azure DNS, you can ensure that your applications and services are easily accessible via the internet.

Azure DNS provides a reliable and scalable solution for managing DNS records. It offers high availability and performance, with global coverage across Microsoft’s data centers. By leveraging Azure’s infrastructure, you can benefit from the reliability and scalability that comes with it.

Benefits of Using Azure DNS:

  • Easy Management: With Azure DNS, managing your DNS records becomes hassle-free. You can easily add, modify, or delete records using the Azure portal or command-line tools.
  • Global Availability: Azure DNS has multiple points of presence across the globe, ensuring low latency and high availability for your domain names.
  • Scalability: Whether you have a small website or a large-scale application, Azure DNS can handle your traffic needs. It automatically scales as per demand without any manual intervention.
  • Tight Integration with Other Azure Services: As part of the Microsoft Azure ecosystem, Azure DNS seamlessly integrates with other services like App Service, Virtual Machines, Traffic Manager, and more.
  • Security: With built-in security features like DDoS protection and role-based access control (RBAC), Azure DNS ensures that your domain names are protected from potential threats.

Azure DNS Zones

In Azure DNS, a zone is a container for hosting one or more domain names. Each zone represents a distinct domain name that you own or manage. When you create a zone in Azure DNS, you need to specify the name of the zone and configure its DNS settings.

Creating a Zone in Azure DNS

To create a zone in Azure DNS, follow these steps:

  1. Sign in to the Azure portal.
  2. Navigate to the Azure DNS service.
  3. Click on “Add zone” to create a new zone.
  4. Enter the domain name for the zone (e.g., example.com).
  5. Configure the DNS settings for the zone, such as name servers and TTL (Time-to-Live) values.
  6. Save the changes and wait for the zone to be created.

Azure DNS Records

Once you have created a zone in Azure DNS, you can add records to it. A record is a mapping between a domain name and an IP address or other resource. There are various types of records supported by Azure DNS, including:

  • A: An A record maps a domain name to an IPv4 address.
  • AAAA: An AAAA record maps a domain name to an IPv6 address.
  • CNAME: A CNAME record creates an alias for another domain name.
  • TXT: A TXT record is used to store arbitrary text data associated with a domain name.
  • MX: An MX record specifies where email messages should be delivered for a domain.

Add Records to an Azure DNS Zone

To add records to an Azure DNS zone, follow these steps:

  1. Navigate to the Azure DNS service in the Azure portal.
  2. Select the desired zone from the list.
  3. Click on “Add record set” to create a new record set.
  4. Choose the type of record you want to add (e., A, CNAME, TXT).
  5. Enter the necessary details for the record (e., name, value).
  6. Save the changes and wait for the record to propagate.


Azure DNS is a powerful and flexible DNS service provided by Microsoft Azure. It offers easy management, global availability, scalability, and tight integration with other Azure services. By using Azure DNS, you can ensure that your domain names are easily accessible and properly configured.

Whether you’re hosting a small website or managing a large-scale application, Azure DNS provides the reliability and performance you need. With its user-friendly interface and extensive documentation, getting started with Azure DNS is a breeze.
