Azure DNS Lesson

What is Azure DNS?

Azure DNS is a hosting service for DNS domains, providing name resolution by using Microsoft Azure's global network of DNS servers. It enables you to manage your DNS records with ease and ensures high availability and performance.

Important: Azure DNS integrates seamlessly with other Azure services, making it a powerful tool for managing DNS in a cloud environment.

Key Features

High availability and reliability
Global reach with low latency
Support for both public and private DNS zones
Easy integration with Azure services
Powerful management tools via Azure Portal and API

Setting Up Azure DNS

Follow these steps to create a DNS zone in Azure:

Log into the Azure Portal.
In the left-hand menu, click on "Create a resource".
Search for "DNS zone" and select it.
Click on "Create".
Fill in the required fields: Subscription, Resource group, Name (your domain), and Region.
Click "Review + Create", then click "Create" again.
Once created, you can add DNS records to your DNS zone.


            // Example: Adding a TXT record using Azure CLI
            az network dns record-set txt create --resource-group MyResourceGroup --zone-name example.com --name mytxtrecord
            az network dns record-set txt add-record --resource-group MyResourceGroup --zone-name example.com --record-set-name mytxtrecord --value "This is a TXT record"

Best Practices

Use Azure Resource Manager templates for deploying DNS zones and records.
Regularly monitor your DNS performance and usage.
Implement DNSSEC for added security.
Keep your DNS records organized and well-documented.

FAQ

What is the difference between public and private DNS zones?

Public DNS zones are accessible over the internet, while private DNS zones are only accessible within a virtual network.

Can I use Azure DNS with my existing domain registrar?

Yes, you can use Azure DNS with your existing domain registrar by updating the name servers to Azure DNS name servers.

How do I secure my DNS records?

You can secure your DNS records using DNSSEC, which adds an additional layer of security through cryptographic signatures.
