In this article, you create a virtual machine in Azure with the Azure portal. The virtual machine is created along with the dual-stack network as part of the procedures. You choose from the Azure portal, Azure CLI, or Azure PowerShell to complete the steps in this article. When completed, the virtual machine supports IPv4 and IPv6 communication.
Prerequisites
- This tutorial requires version 2.0.28 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.
- An Azure account with an active subscription. Create an account for free.
- Azure PowerShell installed locally or Azure Cloud Shell.
- Sign in to Azure PowerShell and select the subscription you want to use. For more information, see Sign in with Azure PowerShell.
- Ensure your Az. Network module is 4.3.0 or later. To verify the installed module, use the command Get-InstalledModule -Name "Az.Network". If the module requires an update, use the command Update-Module -Name "Az. Network".
If you choose to install and use PowerShell locally, this article requires the Azure PowerShell module version 5.4.1 or later. Run Get-Module -ListAvailable Az to find the installed version. If you need to upgrade, see Install Azure PowerShell module. If you're running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

Test SSH connection
You connect to the virtual machine with SSH to test the IPv4 public IP address.
In the search box at the top of the portal, enter Public IP address. Select Public IP addresses in the search results.
Select myPublicIP-IPv4.
The public IPv4 address is in the Overview in IP address. In this example it's, 20.22.46.19.
Open an SSH connection to the virtual machine by using the following command. Replace the IP address with the IP address of your virtual machine. Replace azureuser with the username you chose during virtual machine creation. The -i is the path to the private key that you downloaded earlier. In this example, it's ~/.ssh/mySSHKey.pem.
ssh -i ~/.ssh/mySSHkey.pem azureuser@20.22.46.19
Use az network public-ip show to display the IP addresses of the virtual machine.
az network public-ip show \
--resource-group myResourceGroup \
--name myPublicIP-IPv4 \
--query ipAddress \
--output tsv
user@Azure:~$ az network public-ip show \
> --resource-group myResourceGroup \
> --name myPublicIP-IPv4 \
> --query ipAddress \
> --output tsv
20.119.201.208
az network public-ip show \
--resource-group myResourceGroup \
--name myPublicIP-IPv6 \
--query ipAddress \
--output tsv
user@Azure:~$ az network public-ip show \
> --resource-group myResourceGroup \
> --name myPublicIP-IPv6 \
> --query ipAddress \
> --output tsv
2603:1030:408:6::9d
Open an SSH connection to the virtual machine by using the following command. Replace the IP address with the IP address of your virtual machine.
ssh azureuser@20.119.201.208
Use Get-AzPublicIpAddress to display the IP addresses of the virtual machine.
$ip4 = @{
ResourceGroupName = 'myResourceGroup'
Name = 'myPublicIP-IPv4'
}
Get-AzPublicIPAddress @ip4 | select IpAddress
PS /home/user> Get-AzPublicIPAddress @ip4 | select IpAddress
IpAddress
---------
20.72.115.187
$ip6 = @{
ResourceGroupName = 'myResourceGroup'
Name = 'myPublicIP-IPv6'
}
Get-AzPublicIPAddress @ip6 | select IpAddress
PS /home/user> Get-AzPublicIPAddress @ip6 | select IpAddress
IpAddress
---------
2603:1030:403:3::1ca
Open an SSH connection to the virtual machine by using the following command. Replace the IP address with the IP address of your virtual machine.
ssh azureuser@20.72.115.187
Clean up resources
When your finished with the resources created in this article, delete the resource group and all of the resources it contains:
In the search box at the top of the portal, enter myResourceGroup. Select myResourceGroup in the search results in Resource groups.
Select Delete resource group.
Enter myResourceGroup for TYPE THE RESOURCE GROUP NAME and select Delete.
When no longer needed, use the az group delete command to remove the resource group, virtual machine, and all related resources.
