Hands-On Networking with Azure

By: Mohamed Waly

Overview of this book

Microsoft Azure networking is one of the most valuable and important offerings in Azure. No matter what solution you are building for the cloud, you'll fi nd a compelling use for it. This book will get you up to speed quickly on Microsoft Azure Networking by teaching you how to use different networking services. By reading this book, you will develop a strong networking foundation for Azure virtual machines and for expanding your on-premise environment to Azure. Hands-On Networking with Azure starts with an introduction to Microsoft Azure networking and creating Azure Virtual Networks with subnets of different types within them. The book helps you understand the architecture of Azure networks. You will then learn the best practices for designing both Windows- and Linux-based Azure VM networks. You will also learn to expand your networks into Azure and how to use Azure DNS. Moreover, you will master best practices for dealing with Azure Load Balancer and the solutions they offer in different scenarios. Finally, we will demonstrate how the Azure Application Gateway works, offering various layer-7 load balancing capabilities for applications. By the end of this book, you will be able to architect your networking solutions for Azure.

Azure reverse DNS zone


Reverse DNS is still one of the most important DNS services, and it is no surprise that it is supported in Azure.

If you don't know too much about reverse DNS, in a nutshell, it does totally the opposite of what DNS does. So, instead of translating names to IPs, it translates IPs to names.

Configuring the reverse DNS zone has some slight differences to creating a forward DNS zone, which you will notice when performing the following steps:

  1. Search for DNS zones, and click on Add to add a new one.
  2. Fill the fields in Create DNS zone, as you have learned earlier, with only one change; for the Name field, you will write the DNS domain name IP address in a reverse way:
    • For IPv4, the name is written in the following format: <IPv4 network prefix in reverse order>.in-addr.arpa
    • For IPv6, the name is written in the following format: <IPv6 network prefix in reverse order>.ip6.arpa
