Add Subnet To A Virtual Network Using Azure Management Portal

What is a Subnet?

It’s nothing but a segmentation of a Virtual Network. You can have multiple subnets in a given VNet. Below is a depiction of a Virtual network with two subnets, one of hosting Web Servers (demo-web-snet) and the other (demo-db-snet) for hosting the database Servers.

In one of my previous articles Create Virtual Network (VNet) Using Azure Management Portal, we have created “demo-web-snet” default subnet. Let’s go ahead and create a new subnet named “demo-db-snet”, which will contain all the database related Services.

Navigate to the Virtual Network and click on the network “demo-vnet1” to which we will like to add another subnet.

As shown in the above screenshot, click on the “Subnets” to navigate to the following subnets, which are available in the selected virtual network.

Now, click on the “Subnet” button, as shown in the screenshot, mentioned above, which will navigate to the blade, given below.

Provide a meaningful name and the address range for the subnet, as shown above and click OK button to create the subnet.

After a few seconds, the subnet gets added to the VNet, as shown below.


In this article, we have learned what a Subnet is and how to create a new subnet to an existing VNet. You can read the original article here. I hope you enjoyed reading the article. Your feedback is appreciated.
