Connecting your DNS Provider with Azure Public DNS Zone

Introduction

This guide will take you through how to delegate a sub-domain to Azure DNS zone. If you have a domain with an external provider, this guide will show you how to use Azure DNS zone PaaS to host your sub-domain.

Prerequisites

Guide

Deploy Azure DNS Zone

Login to your Azure subscription and open Cloud Shell (in red box.)

Type in the following commands to create a resource group and Azure DNS zone.

            
                ## Azure CLI
                # Create resource group
                az group create --name MyResourceGroup --location "canadacentral"

                # Create Azure DNS Zone
                az network dns zone create -g MyResourceGroup -n subdomain.parentdomain.ca

                ## PowerShell
                # Create resource group
                New-AzResourceGroup -Name MyResourceGroup -location "canadacentral"

                # Create Azure DNS Zone
                New-AzDnsZone -ResourceGroupName MyDNSResourceGroup -Name subdomain.parentdomain.ca

Delegate Sub-Domain to Azure DNS

Locate the name servers from the output of sub-domain Azure DNS zone creation (in red box.)

In your domain provider’s portal, add NS records with the name servers as the values.

Verify the sub-domain delegation is complete. You can use a tool such as Google Admin Toolbox – Dig.

Note: nslookup command in Cloud Shell might not work if you haven’t configure it to point to anything.
