Networking

Create private networks to connect your instances securely.

Private networks allow instances to communicate internally while remaining isolated.

1. Create a private network

Go to:

Menu → Network → Private Networks

Then:

1. Click Create Network
2. Optionally enter a CIDR
3. Submit the form

Optional CIDR

You can define a CIDR for the network.

Examples:

10.1.5.0/24
10.1.5.0

• If no CIDR is provided, one is assigned automatically
• If /24 is omitted, it is applied automatically
• The platform normalizes CIDR values internally

For most cases, you can leave this field empty.

2. View networks

After creation, networks appear in the list.

You can see:

• Network name
• Network ID

3. Attach a network to an instance

When creating an instance:

1. Select a private network
2. Launch the instance

Instances in the same network can communicate with each other.

4. Control access with security groups

Security groups define firewall rules.

Examples:

• SSH → port 22
• HTTP → port 80
• HTTPS → port 443

See Security Groups Guide

Troubleshooting

Invalid CIDR

Ensure the CIDR is within the allowed range.

Examples:

10.1.5.0/24
10.1.5.0

Instances cannot communicate

Check that:

• Both instances are in the same network
• Security groups allow the required traffic

Network not available

If a network does not appear during instance creation:

• Refresh the page
• Ensure the network was created successfully
