VPCs

A VPC (Virtual Private Cloud) is a logically isolated network in Nebula’s infrastructure. It defines the boundaries for your network resources, making them private and secure.

You can control your own virtual network environment by defining a range of available IP addresses with subnets and network gateways.

Create VPCs

You can create VPCs in 2 ways:

On the VPCs Console page
During the server creation flow

When you create a VPC, you need to define a name and an IPv4 CIDR block. Choose a VPC CIDR block large enough to accommodate all required subnets. Avoid overlap with other networks to prevent routing conflicts.

In simple terms, a CIDR block, or Classless Inter-Domain Routing block helps you allocate a range of IP addresses for your network. A CIDR block consists of these elements:

A base IP address, which is the network identifier for the block.
A subnet mask, or the /x part in the CIDR notation specifies how many IP addresses are available for hosts within the block.

The CIDR block you specify for a VPC is permanent and cannot be modified after creation.

Manage VPCs

You can manage your VPCs via the VPCs Console page.

Select a VPC to see:

the assigned CIDR block
the associated subnets
the attached server instances

You can delete VPCs on the VPC details screen.

You can only delete VPCs that have no associated resources. First, terminate any server instances within each subnet that belongs to a VPC, then delete the subnets. Once all resources are removed, you can delete a VPC.
