You can add an isolated organization VDC network, which is accessible only by this organization. This network provides no connectivity to virtual machines outside this organization. Virtual machines outside of this organization have no connectivity to the virtual machines in the organization.

You can add a mix of isolated and routed organization VDC networks to meet the needs of your organization. For example, you can isolate a network that contains sensitive information and have a separate network that is associated with an edge gateway and connected to the Internet.

You can create an isolated VDC network that is backed by a network pool. Your service provider can also create an isolated VDC network that is backed by an NSX-T logical switch.

You can create only an IPv4 isolated organization VDC network.


This operation requires the rights included in the predefined Organization Administrator role or an equivalent set of rights.


  1. On the Virtual Datacenters dashboard screen, click the card of the virtual data center you want to explore, and select Networks from the left panel.
  2. Click Add.
  3. On the Select Network Type page, select Isolated and click Next.
  4. Enter a meaningful name for your organization VDC network.
  5. Enter the Classless Inter-Domain Routing (CIDR) settings for the isolated network.

    Use the format network_gateway_IP_address/subnet_prefix_length, for example,

  6. (Optional) Enter a description of the organization VDC network.
  7. (Optional) To make the organization VDC network available to other organization VDCs within the same organization, toggle on the Shared option.
    One potential use case for this option is when an application exists within an Organization VDC that has a reservation or allocation pool set as the allocation model. In this case, it might not have enough room to run more virtual machines. As a solution, you can create a secondary Organization VDC with pay-as-you-go and run more virtual machines on that network on a temporary basis.
    Note: The Organization VDCs must be backed by the same Provider VDC.
  8. Click Next.
  9. (Optional) To reserve one or more IP addresses for assignment to virtual machines that require static IP addresses, configure the Static IP Pools for the network.
    1. Enter the IP address or range of IP addresses, and click Add.
    2. To add multiple static IP addresses or ranges, repeat this step.
    3. (Optional) To modify or remove IP addresses and ranges, click Modify or Remove.
  10. Click Next.
  11. (Optional) Configure the DNS settings.
    Option Action
    Primary DNS Enter the IP address for your primary DNS server.
    Secondary DNS Enter the IP address for your secondary DNS server.
    DNS Suffix Enter your DNS suffix. The DNS suffix is the DNS name without including the hostname.
  12. Click Next.
  13. On the Ready to Complete page, review the organization VDC network settings that you have provided, and click Finish.
