In the vast arena of IIoT, industrial routers are not only a bridge connecting the physical world and the digital world, but also a key role in ensuring secure, efficient, and reliable data transmission. As one of the core elements in network configuration, subnet mask settings directly affect the performance, security, and scalability of industrial networks. This article will take you on an in-depth exploration of various settings for subnet masks in industrial routers and their applications in different environments.


I.Basic Knowledge of Subnet Mask

Subnet mask, in short, is a 32-bit binary number used to distinguish the network part and host part of an IP address for IPv4. It uses "1" to represent the network part and "0" to represent the host part, thus achieving a refined division of IP addresses. In industrial networks, a reasonable subnet mask setting is crucial to improving network efficiency, reducing the risk of conflicts, and ensuring data security.

II. Diverse Setting Methods

1.Default setting method

①. Class A network: The default subnet mask is 255.0.0.0, which is suitable for very large networks. Although there are few cases of directly using Class A networks in industrial IoT, understanding its default settings can help to understand the basic logic of subnet masks.


②. Class B network: The default subnet mask is 255.255.0.0, which is suitable for large networks. In large local area networks within factories, Class B networks and their default subnet mask settings are common.


③. Class C network: The default subnet mask is 255.255.255.0, which is suitable for small or medium-sized networks. In most industrial application scenarios, especially small and medium-sized factories or production lines, Class C networks and their default subnet mask settings are more common.


2. Customized setting method

①. Division based on subnet requirements: 

The length of the subnet mask can be customized based on the actual needs of the industrial network. For example, when it is necessary to subdivide the subnet to reduce broadcast domains or improve security, the default subnet mask for a Class C network can be changed from 255.255.255.0 to 255.255.255.128/25, thereby dividing a Class C network into two smaller subnets.


②. Super-network merging: 

On the contrary, when it is necessary to expand the network size and reduce the number of routing table entries, the super-network technology can be used to merge multiple subnets by reducing the number of "1"s in the subnet mask. For example, two adjacent Class C network subnet masks of 255.255.255.0 can be merged into a larger subnet, and the subnet mask can be set to 255.255.255.192/26.


③. dynamic allocation method

In some industrial network environments, especially those that use DHCP dynamic host configuration protocol for IP address allocation, subnet masks may be dynamically assigned to client devices by the DHCP server. This approach simplifies network management and reduces the risk of manual configuration errors.


III. Analysis of Application Scenarios

①. Large factory network: In large factories, due to the large number of devices and wide distribution, the method of combining class B or C networks with custom subnet mask settings is often used to achieve fine management of the network. By dividing multiple subnets, the risk of broadcast storms can be reduced and the overall performance of the network can be improved.


②. Production line automation: In the production line automation system, in order to ensure the real-time and reliable transmission of data, the C-type network and its default or custom subnet mask settings are often used. By optimizing subnet division, network latency and packet loss can be reduced, ensuring the smooth progress of the production process.


③. Remote Monitoring and Diagnosis: In scenarios where remote devices require monitoring and diagnosis, industrial routers are often configured as bridges connecting different subnets or networks. In this case, the setting of subnet masks needs to consider the need for cross-network segment communication to ensure that data can smoothly traverse various network boundaries.


The subnet mask setting of industrial routers is a complex and delicate task, which directly affects the performance, security, and scalability of industrial networks. By flexibly applying different setting methods, we can build an efficient, stable, and secure industrial network environment based on actual needs.

How to Get 5GHz Band Support on Industrial Routers with 802.11b

Obtaining 5GHz band support on industrial routers with 802.11b is not an easy task. Due to the 802.11b standard‘s lack of support for the 5GHz band, it is necessary to achieve this by replacing devices, using dual-band routers or Access Points (APs), or other methods. In the implementation process, it is necessary to comprehensively evaluate the network architecture and actual requirements, select suitable equipment and configuration solutions, and pay attention to issues such as network security and maintenance work.
