Azure Domain Name System (DNS)

It’s not DNS
There’s no way it’s DNS
It was DNS

DNS is a hierarchical and decentralized naming system for any resource connected to a network. It translates domain names to IP addresses needed for locating and identifying services with underlying network protocols. Ever since 1985, DNS has been an essential component of internet functionality.

You’re able to hosting DNS domains by using Microsoft Azure infrastructure. This gives you the ability to manage DNS by using the same credentials, APIs, tools, as well as billing for all of your Azure Services. THe only thing you can’t do (just yet) is buy a domain name using Azure DNS.

Reliable and performant

DNS domain in Azure will be hosted on the global network Microsoft has established with Azure. Azure DNSuses anycast networking, each DNS query being answered by the closest available DNS server to provide fast performance, as well as high availability for your domains.


As Azure DNS is based on Azure Resource Manager, you can use Role-based access control (RBAC) to control who has access, monitor the service using activity logs, and lock down subscriptions, resource groups or resources by Resource Locking.

DNSSec is currently not supported, but the need for DNS sec can be reduced by consistently using HTTPS/TLS in your applications.

Private domains

You can absolutely use Azure DNS to havbe custom domain names in your private virtual networks, rather than the Azure-provided names available by default.

Alias/CNAME records

An alias record set refers to Azure Resources such as Public IP address, traffic manager profiles, or Azure CDN endpoints.
