Subnet

After creating a Virtual Network, you can add one or more Subnets by a process called Subnetting. Subnetting is the process of taking a network and splitting it into smaller networks. This helps you isolate different environments such as production and development.

In the event of a potential attack on a development server, the use of different environment subnets will block access to your production servers.

When you connect your cloud, Bunnyshell imports all your Virtual Networks and Subnets.

Digital Ocean does not support subnets but they support a Private Network. You can look at it as one Virtual Network with one Subnet. Instances from an account can communicate between each other with private IP addresses, while the private network is unreachable from the Internet.

Creating a Subnet

To create a Subnet go to OPS in the left menu, select Virtual Networks and select the Virtual Network where you want to create the Subnet. Click on the right actions button and select Create Subnet.

When you Create a Subnet you have the following fields:

  • Name: The name of your Subnet

  • Address range: CIDR block for your Subnet. Based on your Virtual Network and existing subnets, Bunnyshell will propose an address range that does not collide with existing subnets.

  • Availability zone (AWS Only): AWS allows you to create Subnets in different data centers of your Virtual Network Locations.

Availability zones allow you to create High Available infrastructures that also have low latency in communication.

Removing a Subnet

In order to remove a Virtual Network, go to OPS in the left menu, select Virtual Networks.

Select your Virtual Network and click on the expand button. Click the Remove button for the Subnet you want to remove.

You will not be able to remove a Subnet if Servers are attached to it.
