Quickstart: Create an Azure DNS zone and record using Azure CLI
This article walks you through the steps to create your first DNS zone and record using Azure CLI, which is available for Windows, Mac and Linux. You can also perform these steps using the Azure portal or Azure PowerShell.
A DNS zone is used to host the DNS records for a particular domain. To start hosting your domain in Azure DNS, you need to create a DNS zone for that domain name. Each DNS record for your domain is then created inside this DNS zone. Finally, to publish your DNS zone to the Internet, you need to configure the name servers for the domain. Each of these steps is described below.
Azure DNS also supports private DNS zones. To learn more about private DNS zones, see Using Azure DNS for private domains. For an example on how to create a private DNS zone, see Get started with Azure DNS private zones using CLI.
Use Azure Cloud Shell
Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article without having to install anything on your local environment.
To start Azure Cloud Shell:
|Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell.|
|Go to https://shell.azure.com, or select the Launch Cloud Shell button to open Cloud Shell in your browser.|
|Select the Cloud Shell button on the menu bar at the upper right in the Azure portal.|
To run the code in this article in Azure Cloud Shell:
Start Cloud Shell.
Select the Copy button on a code block to copy the code.
Paste the code into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux or by selecting Cmd+Shift+V on macOS.
Select Enter to run the code.
If you don't have an Azure subscription, create a free account before you begin.
Create the resource group
Before you create the DNS zone, create a resource group to contain the DNS zone:
az group create --name MyResourceGroup --location "East US"
Create a DNS zone
A DNS zone is created using the
az network dns zone create command. To see help for this command, type
az network dns zone create -h.
The following example creates a DNS zone called contoso.xyz in the resource group MyResourceGroup. Use the example to create a DNS zone, substituting the values for your own.
az network dns zone create -g MyResourceGroup -n contoso.xyz
Create a DNS record
To create a DNS record, use the
az network dns record-set [record type] add-record command. For help on A records, see
azure network dns record-set A add-record -h.
The following example creates a record with the relative name "www" in the DNS Zone "contoso.xyz" in the resource group "MyResourceGroup". The fully-qualified name of the record set is "www.contoso.xyz". The record type is "A", with IP address "10.10.10.10", and a default TTL of 3600 seconds (1 hour).
az network dns record-set a add-record -g MyResourceGroup -z contoso.xyz -n www -a 10.10.10.10
To list the DNS records in your zone, run:
az network dns record-set list -g MyResourceGroup -z contoso.xyz
Test the name resolution
Now that you have a test DNS zone with a test 'A' record, you can test the name resolution with a tool called nslookup.
To test DNS name resolution:
Run the following cmdlet to get the list of name servers for your zone:
az network dns record-set ns show --resource-group MyResourceGroup --zone-name contoso.xyz --name @
Copy one of the name server names from the output of the previous step.
Open a command prompt, and run the following command:
nslookup www.contoso.xyz <name server name>
nslookup www.contoso.xyz ns1-08.azure-dns.com.
You should see something like the following screen:
The host name www.contoso.xyz resolves to 10.10.10.10, just as you configured it. This result verifies that name resolution is working correctly.
Delete all resources
When no longer needed, you can delete all resources created in this quickstart by deleting the resource group:
az group delete --name MyResourceGroup
Now that you've created your first DNS zone and record using Azure CLI, you can create records for a web app in a custom domain.
