Virtual network

Overview​

A virtual network is the private network that VMs belong to. The IP range is defined by a CIDR block, and VMs in the same virtual network can talk to each other over private IPs.

Creating a virtual network​

  1. Under Network > Virtual Networks, click Create Virtual Network.

  2. Configure the following:

    FieldDescriptionExample
    Virtual network nameAn identifying nameprod-vnet
    Network CIDRIP range (must be inside 172.16.0.0/14 or 192.168.0.0/16)192.168.0.0/16

  3. Click Create.

CIDR tips
  • ECI only allows CIDRs inside 172.16.0.0/14 (172.16.0.0–172.19.255.255) or 192.168.0.0/16 (RESOURCE_SUBNET_ALLOWED_NETWORK_CIDRS).
  • If you plan to create many VMs, size up to /16 (65,534 IPs).
  • After creation, CIDR and zone cannot be changed (editable: name, tags, firewall rules).

Managing virtual networks​

  • List: shows name, CIDR, and number of subnets
  • Delete: only possible if no subnets or VMs are attached
