An IP address is an individual identifier that makes it possible to identify a specific device within a network , whether locally or on the Internet. Similar to telephone numbers or car license plates, it is used to localize the location of a device and make it accessible for communication purposes.
The Internet Protocol (IP) defines the rules according to which data is sent via the Internet or local networks. It determines the format of this data and thus ensures a smooth exchange between different devices.
Types of IP addresses
IP addresses can be divided into different categories. On the one hand, there are public and private IP addresses. Public IP addresses are uniquely identifiable on the Internet and enable communication between devices via the World Wide Web. Private IP addresses, on the other hand, are used for internal communication within private networks and cannot be accessed directly from the Internet.
Furthermore, there are distinctions between IPv4 and IPv6 – v4 or 6 simply stands for version4 or version6. IPv4 uses a 32-bit address and thus enables around 4.3 billion unique addresses. However, due to the exponential increase in networked devices, IPv4 is reaching its limits, which is why the newer IPv6 with its 128-bit addresses was developed to meet this demand.
IP addresses can also be static or dynamic. Static IP addresses remain unchanged and are permanently linked to a specific device, while dynamic IP addresses can be reassigned as required.
The connection to the MAC address
In addition to the IP address, each network device also has a so-called MAC address (Media Access Control). It is firmly anchored in the hardware of the device and is used to uniquely identify it in the local network.
The connection between IP address and MAC address is that the MAC address operates on the physical level, while the IP address operates on the logical level of the network. When a device sends data, the IP address is used to identify and localize the target device. The corresponding MAC address is then used to transmit the data on the physical level of the network.
IP addresses are therefore the backbone of modern digital communication. They make it possible to connect devices with each other, exchange data and use the Internet. The connection to the MAC address ensures smooth transmission of information in the network.
MAC stands for Media Access Control. A MAC address is a unique identifier that is assigned to each network device. This address, which consists of a 48-bit number combination, uniquely identifies each network interface in a network. The MAC address is usually displayed in hexadecimal form, which means that it consists of numbers and letters. Interestingly, the MAC address is divided into two parts: The first 24 bits identify the manufacturer of the device, while the remaining 24 bits identify the individual device.
MAC addresses play a decisive role in networks. In order to receive a signal from another device, the receiving device must have a unique MAC address. Without this, the data sent would come to nothing. The MAC address is therefore to be understood analogously to a house number, which enables the resident to receive mail. In addition, network administrators can use MAC addresses to control access to the network. By authorizing or blocking certain MAC addresses, you can ensure that only authorized devices can access the network. This improves network security by preventing unauthorized access.
How do I find the MAC address of my device?
It is relatively easy to read out the MAC address of your device; this is usually written on the inside of the network sockets. The method of reading the MAC address from the software varies depending on the operating system:
Under Windows, you can find the MAC address in the “Status” of a network connection on the “Network support” tab in the “Details” or use the “ipconfig/all” command in the command line.
Under Linux, execute the command “ifconfig” in the terminal to see the “HWaddr” (hardware address).
On a device with Mac OS, you can either use the “ipconfig” command in the terminal or find the MAC address in the “Network” area of the system settings.
In summary, it can be said that MAC addresses play an essential role in communication between devices in e networks, whereas on the Internet, devices are mainly identified via IP addresses .
MAC addresses at spo-comm
With regard to your order with spo-comm, we can provide you with the MAC addresses for your order on request.
The year 2024 marked the start of a new product category for us. An 18″ and a 21″ panel PC have also been available in our spo-comm product portfolio since January.
Both the SQUARE 18 and the SQUARE 21 shine above all with their customizable CPU (an Intel® Core™ i3-1115G4E or Intel® Celeron 6305E CPU), which is supported by up to 32GB DDR4 RAM and up to 2TB of M.2 NVMe SSD is supported. With their 18″ or 21″ multi-touch display and wide range of connections, our fanless panel PCs are ideal for use as digital signage players and at the PoS in retail.
Bye bye CORE 2 – EOL for our digital signage player
After almost four and a half years, it’s time to say goodbye to our ultra-compact digital signage mini PC. Unfortunately, the CORE 2 is no longer available from us.
But of course we can’t do anything without CORE – the successor to our all-time DS star is already in the starting blocks and has already been christened “CORE 3”.
Space for something new – price reduction at KUMO, BRICK & Co.
A few of our PCs will soon have to make room for new models, so we are reducing the prices!
The following models are now available at a reduced price:
We encounter countless electronic devices in modern industry and in everyday life. Whether controllers in production, outdoor lighting or robust mini PCs for the control cabinet – they all have to function reliably, even under demanding conditions. This is exactly where IP protection classes come into play. They indicate how well a device is protected against the ingress of dust, dirt and water.
What does IP mean?
The letters “IP” in the IP protection class stand for “Ingress Protection” or “International Protection”.
Ingress Protection describes the degree of protection of a device against the ingress of foreign bodies and liquids.
International Protection indicates that these types of protection are defined worldwide according to standards (IEC 60529).
The IP classification ensures that manufacturers and users can objectively compare the resistance of devices, regardless of brand and model.
Structure of the IP protection class
It consists of two digits:
First digit (0-6) – Protection against solid foreign bodies: dust, dirt, contact. Second digit (0-9K) – Protection against water: dripping water, splashing water, water jets or submersion.
For example: IP65
6 = dust-tight ; 5 = protection against water jets from all directions
This combination indicates that the device is both fully protected against dust and resistant to water jets that hit the device from any direction.

Typical applications of IP protection classes
IP20: For dry indoor areas such as offices or server rooms.
IP44: Suitable for workshops or bathrooms, protection against splashing water.
IP65: Ideal for outdoor areas, warehouses and industrial production environments as it resists dust and water jets.
IP68: For underwater devices or applications with permanent exposure to liquids.
The correct selection of the IP protection class ensures that devices function reliably under the respective environmental conditions and that the failure rate is minimized. Denios has explained the applications for IP protection classes in more detail in an article.
Why IP protection classes are important
The IP classification is not just a marketing label – it is a decisive criterion when selecting devices:
Durability: Devices that cannot withstand environmental stress wear out more quickly.
Safety: Electrical devices that are damaged by water or dust can cause short circuits or failures.
Planning security: IP classes enable an objective selection of devices for specific areas of application, whether in industry, outdoors or in medical facilities.
IP protection classes for industrial PCs and control cabinet PCs
IP protection is particularly important in industry:
Control cabinet PCs are often operated in harsh environments where dust, vibrations or splash water occur.
Robust enclosures, often with DIN rail mounting, reliably protect electronics.
IP65 or higher is common for devices that are used directly in production lines.
This enables companies to ensure that their control systems, machine PCs or industrial tablets work permanently and reliably – without the devices being damaged by external influences.
Conclusion and spo-comm products with IP protection classes
IP protection classes provide a clear, standardized indication of how well a device is protected against dust and water. Whether for private, commercial or industrial use – choosing the right IP class is crucial for the safety, reliability and service life of electronic devices. Particularly in areas such as industrial PCs, control cabinet PCs or outdoor applications, users should always pay attention to the right protection class in order to avoid expensive failures.
Keywords such as IP protection class are no longer a rarity in our product portfolio either; the SQUARE 18, SQUARE 21 and our RUGGED tablets, for example, are IP 65 dust and water-protected. In addition, some RUGGED tablets are even MIL-STD-810G certified. This certification is a US military standard that defines the suitability of equipment for use in military applications.
We say goodbye to our smallest Mini-PC, the BOX N4100. But her successor is not long in coming. In terms of design, basically nothing has changed here, but there are small but significant changes in terms of technical data. The BOX N6211 comes with an Intel® Celeron® N6211 CPU, 8GB integrated RAM and a 128GB eMMC SSD. Like its predecessor, the new BOX N6211 is ideal for digital signage applications thanks to its various interfaces.
It’s that time again, just like last year in June, we are organizing a team event again this year. Our teams update each other on the latest developments and we take new employee photos. Afterwards, we will end the afternoon in a relaxed atmosphere by taking advantage of the good weather, firing up the barbecue and reviewing the last six months together. Preparations for this are currently in full swing and we are looking forward to a great day together and good conversations! For this reason, we are unfortunately not available for you on Thursday, 22.06.23!
We are ISO-certified again!
At spo-comm’s Nuremberg headquarters, the ISO audit, which ensures that companies comply with certain quality standards, was on the agenda this spring. This was again successful in 2023. We have already explained exactly what this ISO certification is in an article at .
On Wednesday, 03.05. our two trainees Patricia and Maxim have completed this year’s rollout of the High-Octane Motorsports where the new racing car for the 2023 season was presented. Some of our student assistants are active members of this student association at FAU Erlangen.
As a proud sponsor, we as spo-comm were also immortalized on the new FAUmax Pi along with many other sponsors!
The Octanes enjoy a new KUMO VI, which is installed in the FAUmax PI and is responsible for autonomous driving.
After a long pandemic break, an event for the entire spo-comm team is finally taking place again this year.
On Thursday, 22.06.2023 we are therefore unfortunately not available for you!
End of Life: WINDBOX III Evo becomes III Ultra
We presented the latest system in the WINDBOX series at the beginning of March. The WINDBOX III Ultra now replaces the WINDBOX III Evo. Like its predecessor, the model was developed for use in industrial environments. But the WINDBOX III Ultra can also score points in the digital signage sector with its 2 HDMI and 2 DisplayPorts.
About the WINDBOX series:
The models in the WINDBOX series are all true all-rounder PCs. These systems were developed in collaboration with the Taiwanese industrial PC manufacturer MSI IPC. Thanks to the passive cooling, slim design and powerful processors, these mini PCs can be used in industry or logistics as well as in the digital signage sector.
Windows 10 Pro (version 21H2) is also no longer available in our online store. The last security updates for this version will be available on June 13, 2023 and it can no longer be purchased.
If you want to equip your system with an operating system, we have the following options for you in our store:
Windows 11: Some of our systems can be equipped with Windows 11, including WINDBOX III Ultra, KUMO VI, MOUNT Silver, NINETEEN Q370, BOX J4125, CORE 2 and RUGGED Ryzen

The NVMe specification
The Non-Volatile Memory Express (NVMe) is a communication protocol that was specially developed for working with flash memory via the PCIe interface. NVMe takes advantage of the parallel nature of solid state drives, enabling the highest throughput and fastest response times to date for all types of workflows.
NVMe storage is perfect for business scenarios where every second counts. For example, in real-time customer interactions in areas such as finance, e-commerce and software sales. But also applications in the fields of artificial intelligence, machine learning, big data and advanced analytics.
NVMe over Fabrics
NVMe over Fabrics (NVMe-oF) is a further development of the NVMe standard. It defines the level of a network distributor (the “fabric”) between the NVMe device and the PC (or the PCIe bus). This makes it possible to detach the mass storage devices from a computer and thus increase utilization and availability.
Different designs of SSDs
There are basically three different types of SSDs:
2.5” and 3.5”
M.2
mPCIe
The NVMe is based on the M.2 design and is therefore long and slim, whereas the mPCIe SSD is slightly wider and therefore shorter. The 2.5” (70 x 100 mm) and the 3.5” SSD (101.6 x 146.05 x 25.4 – 41.4 mm) are the largest of the three shapes and take up the most space in the PC (see Fig. 1, source: computer-bild.de)
SATA and PCIe transfer protocols
A distinction is made here between SATA and PCIexpress.
The SATA transfer protocol is compatible with all three designs and has the following designations: 2.5” SATA connection; M.2 SATA and mSATA. They all transmit at 6Gbit/s, i.e. around 500 mbyte/s.
There are different versions of the PCIexpress transfer protocol, starting from 1.0 up to 5.0, with different speeds in ascending order. One M.2 PCIe always has 4 lanes, including the Non-Volatile Memory Express. An NVMe as found in our spo-comm Mini-PCs transfers at 9.8 GBytes/s, as we are using an M.2 PCIe 3.0 with 4 lanes speak.
spo-comm Mini-PCs with NVMe:
Our product range includes two Mini PCs that can be equipped with an NVMe SSD. One is our KUMO VI, which is at home in the field of sophisticated digital signage applications. The NINETEEN Q370, an industrial PC par excellence, can also be optionally equipped with NVMe.
A long-time companion of our spo-comm product portfolio in the areas of digital signage and industrial control has unfortunately had to leave us. The NOVA Q170, which we developed together with our Taiwanese partner MSI, is no longer available. It was most notable for its versatility, was equipped for use in harsh environments and, thanks to its graphics card, was also ideal for digital signage.
Of course, our range offers plenty of attractive alternatives, such as our WINDBOX series or the RUGGED GTX1050TI. If you have any questions about a replacement product for the NOVA Q170, please do not hesitate to contact us.
Thanks to the newly integrated appointment booking tool on our website, it is now even easier for our customers and interested parties to arrange a telephone consultation appointment.
Whether you have questions about our products or other offers, such as our various Windows IoT packages or customizing solutions. Via our contact page , you can make an appointment with our customer advisors in just a few clicks, where we can take care of your request together.
As the name suggests, the Semi-Annual Channel brings a new release with new Windows Server versions twice a year. These SAC versions are primarily intended for customers with rapid innovations (according to Microsoft).
The first SAC release was System Center version 1801. The names of the versions always depend on the release year and its month, so the first release was version 1801, as it was released in January 2018. From the time of public availability, the semi-annual channel versions are supported by Microsoft for 18 months. This channel is only offered to customers with Software Assuarance and corresponds to the release and maintenance model for Windows servers, which was announced in 2017.
What is LTSC?
LTSC is the abbreviation for the Long-Term Servicing Channel and, like SAC, was introduced with Windows Server 2016. Basically, LTSC has always existed, it was just not called that until the introduction of SAC. In the LTSC, there are both large, chargeable upgrades (major releases) and small updates such as patches etc.. They close security gaps, improve stability and fix minor bugs. LTSC offers five years of mainstream support and a further five years of extended support. This channel is best suited for systems that require a longer maintenance option and functional stability. The LTSC releases contain the full range of Windows Server functions, i.e. Core, Nano Server and Desktop, and are usually released every two to three years.
Our spo-comm Mini-PCs are all equipped with Windows LTSC, Windows 10 or 11 makes no difference here.
