Vultr has renamed Private Networking to Virtual Private Cloud (VPC). You'll see both VPC and Private Network in our documentation during this transition. These are the same feature; only the name has been changed.
A Vultr Virtual Private Cloud (VPC) is an easy-to-configure private network system with powerful configuration tools. With a Vultr VPC, you can create shared or segmented private networks.
You can use a VPC to segment your cloud servers into logical groups or harden your public interface while allowing permissive access from other cloud servers in the same VPC. You can run your backups, replication, and other back-end tasks in complete privacy without exposing the traffic to the public internet.
VPCs are entirely private, even from each other. Other customers cannot see traffic on your VPC private network, and your VPCs cannot pass traffic to each other. If you need to pass traffic between your VPCs or to another customer's VPC, you can set up VPC peering. See the VPC Peering guide for more details.
We provide network configuration examples for many popular operating systems on the server's Settings page. Select IPv4, and then follow the networking configuration link to view the examples.
Note: Your network adapter name may not match these examples. See How to Find the Network Adapter Names for a Vultr Cloud Server to learn more.
We also have generic examples for these operating systems:
Choose Add VPC Network.
Select a location.
Accept an automatic IP range or configure it manually. If you choose manual configuration, you'll find a helpful link to our subnet calculator.
You can use any RFC1918 private address range, 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16. When you attach Vultr products such as Load Balancers to the VPC, they will automatically choose non-conflicting addresses.
In most cases, you should choose the Auto-Assign option in Manage Routes. If your configuration requires advanced configuration, choose Configure Custom Routes and use the Set Routes section.
Give the VPC a name and click Add Network.
After you've created a VPC, you can assign it to an instance. To be compatible with other Vultr products, like Load Balancers, use addresses in the same range you chose in step 6.
Navigate to the server Settings page and click IPv4. If you haven't created a VPC yet, use the Manage link to create one. You'll find it next to the VPC Network title.
The server will reboot to activate the network adapter.
The Vultr API offers several endpoints to manage VPCs.
These guides explain how to use multiple VPCs, and multiple public IPs, on a cloud server instance.
