Switch your Public DNS zone to Azure DNS

October 29, 2020 · Joe Stocker

Recently we experienced an issue with Cloudflare DNS. I opened a support ticket but they were unable to explain why some locations around the world were unable to resolve our DNS MX records.

This was causing non-deliverable email problems so we decided to switch to Azure DNS.

Step 1 – Export the DNS Zone from Cloudflare (Advanced –> Export)

Step 2 – Create the DNS Zone in Azure

I prefer using the Web Interface (here)

Step 3 – Import the zone file into Azure DNS

Install Azure CLI from (here)

Launch PowerShell
#Login to Azure CLI
az login
#List your Subscriptions
az account list
#Select a Subscription
az account set --subscription "My Demos"
#Make sure you see the DNS Zone that you created in step 2
az network dns zone list
#Import Zone from file (Documentation is here)
az network dns zone import -g MyResourceGroup -n mysite.com -f zone.txt

PowerShell Alternative to Azure CLI

Don’t like Azure CLI? You can also manage your zone with the regular PowerShell module:
Install-Module -Name AzureRM.Dns -Force
Install-Module -Name AzureRM.Network -Force
Connect-AzureRmAccount
Get-AzureRmSubscription
Select-AzureRmSubscription -SubscriptionName "My Demos"
Get-AzureRmDnsZone
