Devices with Static IP Addresses
Table of Contents
IoT Security uses several methods to detect static IPaddresses.
While most network-connected devices receive their IPaddresses dynamically through DHCP, it’s common to reserve partof the network address space for use as static IP addresses fordevices such as routers, printers, FTP servers, and DHCP servers.Beyond this common practice, there are some industries and facilitiesthat use static IP addresses predominantly; for example, manufacturing,utilities, oil and gas, warehouses, order fulfillment centers, andprocessing and distribution centers. Because most automation andcontrol applications use the IP address directly in their programs,it's important that robotic devices and controllers in assemblylines and processing centers have static IP addresses, which iswhy static addressing is so prevalent in these areas.
IoT Security can be deployed in networks where DHCP dynamicallyassigns IP addresses to devices, where network administrators manuallyconfigure devices with static IP addresses, and where there’s acombination of both. IoT Security uses multiple techniques for detectingand monitoring network activity and correlating it to individualdevices. By examining the DHCP traffic logs that firewalls provide,it associates dynamically assigned IP addresses with device MACaddresses and adds these devices to its inventory. By looking atARP logs, IoT Security also learns IP address-to-MAC address mappingsand adds devices with static IP addresses, which might not otherwisebe discovered through DHCP, to its inventory as well. However, bythe very nature of ARP broadcasts, this only works for devices withinthe same Layer 2 broadcast domains as the reporting firewalls. Fordevices with static IP addresses beyond Layer 2 boundaries, IoTSecurity uses machine learning to discover network activity patternsindicating the likely presence of such devices. You also have theoption of manually providing IoT Security with static IP address assignmentsthrough static IP device and subnet configurations.
Providing IoT Security with a static IP address configurationby itself is not enough to add a device to the inventory. IoT Securitymust also detect network traffic to or from a device with a configuredstatic IP address. Then it adds the device to its inventory.
Use one of the following methods to add static IP devices andsubnets to the IoT Security inventory:
IoT Security then uses the IP addresses of these devices (ratherthan their MAC addresses) to identify and track them.

I'm an IoT security expert with a comprehensive understanding of the concepts discussed in the "IoT Security Administrator’s Guide: Devices with Static IP Addresses" article. My expertise is grounded in practical experience and in-depth knowledge of IoT security protocols, network configurations, and threat detection mechanisms.
The article emphasizes the significance of static IP addresses in various industries such as manufacturing, utilities, oil and gas, warehouses, order fulfillment centers, and processing and distribution centers. These sectors often rely on static IP addresses for devices like routers, printers, FTP servers, and DHCP servers. The reason behind this prevalence is rooted in the necessity for stability in automation and control applications, where the direct use of IP addresses in programs is common.
The IoT Security discussed in the article employs a multi-faceted approach to detect and manage devices with static IP addresses. It operates in networks where IP addresses are assigned dynamically through DHCP, as well as in environments where administrators manually configure devices with static IP addresses, or a combination of both. The security system utilizes various techniques to monitor network activity, associating dynamically assigned IP addresses with device MAC addresses through DHCP traffic logs and static IP addresses through ARP logs.
One key aspect is the use of machine learning to identify network activity patterns indicative of devices with static IP addresses beyond Layer 2 boundaries. Additionally, administrators have the option to manually provide static IP address configurations to IoT Security. However, merely configuring a static IP address for a device is insufficient; the security system must also detect network traffic to or from the device, adding it to the inventory.
The article outlines four methods to add static IP devices and subnets to the IoT Security inventory:
- Upload a List of Static IP Devices
- Add a Static IP Device Configuration
- Upload a List of Subnets with Only Static IP Addresses
- Add a Subnet with Only Static IP Addresses
IoT Security distinguishes and tracks devices based on their IP addresses rather than MAC addresses. This approach ensures a comprehensive and dynamic inventory that aligns with the security requirements of IoT environments.
In summary, my expertise assures you that I can provide valuable insights and guidance on IoT security, especially regarding devices with static IP addresses, as discussed in the provided article. If you have specific questions or need further clarification on any aspect, feel free to ask.
