# Working with Organization VDC Networks
## **Overview**
Organization virtual data center (VDC) networks enable vApps\VMs to communicate with each other or with external networks outside the organization.
Depending on the connection of the organization VDC network, there are several different types of organization VDC networks:
* **An isolated (internally connected) network** is one that only VMs within the VDC network can connect to.
* **A routed network (externally connected)** provides access to machines and networks outside the VDC via the edge gateway.
## **Procedure**

{% step %}
**Step 1:** Creating an Isolated VCD Network
* In the top navigation bar, click **Networking**.
* On the *Networks* tab, click **New** to Open New Organization VDC Network window.
* On the *Scope* page, select **Organization Virtual Data Center** or **Data Center Group** which to create the network, and click **Next**
* On the *Select Network Type* page, select **Isolated** >> **Next**.
* Enter a **Name and** **description** (optional) for the network.
* To enable dual-stack networking (enable the network to have both IPv4 & IPv6 subnet), turn on the **Dual-Stack Mode** toggle.
* Enter the Classless Inter-Domain Routing (CIDR) settings for the network >>**Next**
Format: network\_gateway\_IP\_address/ subnet\_prefix\_length like *192.168.100.254/24*
* In *Static IP Pools*, enter the ranges of IP addresses that you want to use, click **Add** >> **Next**
* Configure the DNS settings (Optional).
You can put Primary DNS\Secondary DNS\DNS suffix >> **Next**
* Review your settings and click **Finish**.
{% endstep %}
{% step %}
**Step 2**: Creating a Routed VCD Network
* In the top navigation bar, click **Networking**.
* On the *Networks* tab, click **New** to Open New Organization VDC Network window.
* On the *Scope* page, select **Organization Virtual Data Center** or **Data Center Group** which to create the network, and click **Next**
* On the *Select Network Type* page, select **Routed** >> **Next**.

**Step 3:** View the Available Organization VDC Networks
* In the top navigation bar, click **Networking**.
* In the **Networks** tab, you will see a list of the available networks that you can also edit, increase the scope, or delete the Organization VDC network
