Manage Subnets

Virtual Subnets in WiLine Edge Cloud (WEC) define segmented network ranges inside a Virtual Private Cloud (VPC). They are used to isolate workloads, organize IP allocation, and control internal network architecture.

The Subnets dashboard provides both a high-level summary and a detailed table of all subnets across your environment.

At the top, you’ll see key statistics:

  • Total Networks — total number of subnets across all zones
  • Active Networks — percentage of subnets currently implemented
  • VPC Networks — number of VPCs associated with subnets
  • Data Transfer — total network traffic across all subnets

View Subnets​

After logging in to the WiLine Edge Cloud:

  • Navigate to Networks → Subnets.

You will see a dashboard with summary metrics and a table listing all subnets:

Subnets dashboard Figure 1: Subnets dashboard displaying subnet metrics and network overview.

Below the statistics, you’ll find a table listing all subnets.

Each row represents a subnet and includes:

  • Network Name — subnet identifier
  • Status — implementation state (e.g. Implemented)
  • Network Range — CIDR block and IP range
  • Zone — deployment location
  • VPC — associated Virtual Private Cloud
  • Created — creation timestamp

Filters​

The table can be filtered using multiple dimensions:

  • States — filter by subnet status
  • Zones — filter by deployment location
  • VPCs — filter by associated VPC
  • Accounts — filter by account ownership

These filters help narrow down network visibility in large environments.

Display Options​

You can customize the table view:

  • Show or hide columns
  • Adjust visible network attributes
  • Improve readability based on operational needs

Actions column​

In each row, clicking the icon opens the Network Actions menu:

Available actions include:

  • Edit Network — modify subnet configuration (CIDR, metadata)
  • Configure — access advanced subnet settings
  • Delete Network — permanently remove the subnet
note

Available actions may be enabled or disabled depending on subnet state and dependencies such as attached instances or routing rules.

:::warning Cannot Delete Subnet

Subnet deletion is blocked when virtual machines are still attached.

If instances exist, the system prevents deletion and shows a confirmation modal listing affected VMs.

Modal includes:

  • Message: Cannot delete subnet, resources still present
  • Attached virtual machines (name, status, OS, zone, IP)
  • Actions:
    • View Virtual Machines (filtered by subnet)
    • Cancel

To proceed:

  1. Remove or terminate all virtual machines in the subnet
  2. Ensure no remaining resources use the subnet range
  3. Retry deletion once the subnet is empty

Manage Subnets​

To manage a subnet:

  1. Locate the subnet in the table (see View Subnets)
  2. Use filters if needed to refine results
  3. Click the in the Actions column
  4. Select the desired action (Edit, Configure, or Delete)

Subnet Details​

Each subnet represents a segmented IP range inside a VPC. In this environment:

  • Subnets define network boundaries within a VPC
  • Each subnet is assigned a CIDR block (e.g. 10.80.4.0/24)
  • Subnets are associated with a zone for physical or logical placement
  • Subnets can contain instances and network services

Example: Subnet Entry​

  • Name: Default Subnet
  • Status: Implemented
  • Network Range: 10.80.4.0/24
  • IP Range: 10.80.4.0 - 10.80.4.255
  • Zone: Princeton, USA
  • VPC: Default-VPC
  • Created: Apr 8, 2026

Key Concept​

Subnets are the building blocks of VPC networking, allowing you to:

  • Segment networks for security and organization
  • Allocate IP ranges to specific workloads
  • Control where resources are deployed within a VPC
