Private IP Addresses in Cloud Infrastructure
1.0 Overview
IoT Secure is committed to delivering secure, efficient, and transparent solutions to our customers. Recently, some customers have raised concerns after noticing unfamiliar IP addresses in their network logs. This article explains how IoT Secure assigns a unique IP address to each appliance and why these addresses should not be a cause for concern.
2.0 Use of Unique Private IP Addresses for Each Appliance in PortSafe™ Infrastructure
To ensure the security and efficiency of our multi-tenant cloud environment, each IoT Secure appliance is assigned a unique IP address in the 1.x.x.x range. This address is essential for identifying and securely communicating with your appliance. Here’s a breakdown of how and why we use these addresses:
- One appliance, one unique IP: Every IoT Secure appliance is assigned a single, dedicated 1.x.x.x IP address during the manufacturing process. This IP address is unique to your device and is exclusively used for secure communications within IoT Secure’s system.
- Internal use only – no public routing: The 1.x.x.x IP address assigned to your appliance is for internal use only. It is not routed over the public internet and is used purely for internal communication between your appliance and our Cloud Data Center.
- No external connections: The assigned 1.x.x.x IP
addresses are not used for any external communication and do not
represent foreign or external access attempts. These addresses are part
of IoT Secure’s secure internal network.
- Avoiding network conflicts: Traditional internal IP spaces, such as those defined by RFC1918 (10.x.x.x, 172.16.x.x, and 192.168.x.x), are widely used in corporate networks. To prevent conflicts with customer-assigned IPs, we use a unique 1.x.x.x address for each appliance. This ensures that your organization’s internal network and IoT Secure’s appliance network remain completely separate and do not interfere with one another.
3.0 Technical Rational
- Why the 1.x.x.x range?: While 1.x.x.x addresses are typically public IPs, IoT Secure uses them internally to avoid overlaps with private IP ranges commonly used in customer networks. This means that even though the 1.x.x.x range is technically a public IP space, we treat it as a private, internal-only range within our secure network. These IPs are never advertised or exposed outside of IoT Secure’s infrastructure, making them safe and isolated from external networks.
- Network isolation and encryption: All communications between your appliance and our Cloud Data Center are encrypted using industry-standard protocols to ensure the security of your data. The use of a unique 1.x.x.x address per appliance guarantees that each device is securely and individually identified within our network.
4.0 Unique Appliance Identification Using 1.x.x.x Addresses
To make appliance identification easier, each device’s unique 1.x.x.x IP address is clearly printed on a sticker, both on the side of the appliance box and on the appliance itself. This allows you to quickly identify the specific IP address associated with your device.
5.0 Ensuring Customer Confidence
IoT Secure’s infrastructure is designed with strong security measures, including encryption, to protect all data transmitted between your appliance and our Cloud Data Center. The assignment of a unique 1.x.x.x IP address to each appliance is part of this secure design, ensuring proper communication while maintaining the privacy of your network.
