How to set up VPC networking on DigitalOcean

intermediate 8 min read Updated 2026-04-20
Quick Answer

Setting up VPC networking on DigitalOcean involves creating a Virtual Private Cloud through the networking panel, configuring IP ranges, and connecting droplets to the VPC for secure internal communication. This allows resources to communicate privately without using public internet traffic.

Prerequisites

  • Active DigitalOcean account
  • Basic understanding of networking concepts
  • SSH key configured for droplet access
  • Familiarity with DigitalOcean control panel

Step-by-Step Instructions

1

Access the VPC Section

Log into your DigitalOcean control panel and navigate to Networking from the left sidebar. Click on the VPC tab to access the Virtual Private Cloud management interface.
Make sure you're in the correct project if you have multiple projects configured.
2

Create a New VPC

Click the Create VPC Network button. Enter a descriptive name for your VPC in the VPC Name field. Select your preferred datacenter region from the Region dropdown menu.
Choose a region close to your users for better performance and ensure all resources are in the same region.
3

Configure IP Range and Settings

Set the IP range for your VPC using CIDR notation in the IP Range field (default is 10.116.0.0/20). You can customize this range based on your needs. Leave the Description field optional or add notes about the VPC's purpose.
Use private IP ranges like 10.x.x.x, 172.16-31.x.x, or 192.168.x.x to avoid conflicts with public IPs.
4

Review and Create VPC

Review your VPC configuration settings including name, region, and IP range. Click Create VPC Network to finalize the creation. The VPC will appear in your networking dashboard within a few seconds.
5

Create Droplets in the VPC

Navigate to Create > Droplets to create new droplets. In the droplet creation form, scroll to the VPC Network section and select your newly created VPC from the dropdown. Configure other droplet settings as needed.
You can create multiple droplets in the same VPC for them to communicate privately.
6

Configure Droplet Networking

Complete the droplet creation process. Once created, your droplets will have both public IP addresses and private VPC IP addresses. Access your droplet via SSH using ssh root@your-droplet-ip to verify network configuration.
Use the private IP addresses for communication between droplets in the same VPC to avoid data transfer charges.
7

Test VPC Connectivity

From one droplet, test connectivity to another droplet in the same VPC using the private IP: 
ping 10.116.0.x
Replace the IP with your target droplet's private VPC IP address. Successful pings confirm proper VPC networking setup.
Configure firewall rules using DigitalOcean Cloud Firewalls to control traffic between VPC resources.
8

Add Existing Resources to VPC

To add existing droplets to your VPC, go to the droplet's Networking tab and click Add to VPC. Select your VPC from the list and click Assign VPC. The droplet will be assigned a private IP within the VPC range.
Adding existing droplets to a VPC may require a reboot for network changes to take effect.

Common Issues & Troubleshooting

Droplets cannot communicate within VPC

Check that both droplets are in the same VPC network and region. Verify firewall settings allow internal traffic and ensure you're using private IP addresses for communication.

VPC creation fails with IP range error

Ensure you're using valid private IP ranges in CIDR notation. Avoid conflicts with existing VPCs in the same region by choosing different IP ranges like 10.117.0.0/20.

Cannot add existing droplet to VPC

Verify the droplet is in the same region as the VPC. Some older droplets may not support VPC networking - consider creating new droplets if the option is unavailable.

High data transfer costs between droplets

Ensure you're using private VPC IP addresses for internal communication instead of public IPs. Traffic within a VPC doesn't incur bandwidth charges between droplets in the same datacenter.
