DHCP Device Type: MSFT 50
Understanding the DHCP Request
DHCP (Dynamic Host Configuration Protocol) plays a crucial role in assigning IP addresses and other network configuration settings to devices connected to a network. When a device connects to a network, it sends a DHCP request to a DHCP server. This request includes various information, including the vendor class identifier (VCI).
MSFT 50: A Windows Device
MSFT 50 is a VCI that identifies a device as a Windows computer. When you see MSFT 50 in a DHCP request, it indicates that the device making the request is likely a Windows-based device, such as a laptop or desktop PC.
dhcpcd-5.5.6: An Android Device
dhcpcd-5.5.6 is another VCI that identifies a device as an Android device. When you see dhcpcd-5.5.6 in a DHCP request, it indicates that the device making the request is likely an Android-based device, such as a smartphone or tablet.
Identifying Device Type Using Light Cat
Light Cat is a network monitoring tool that can be used to analyze network traffic, including DHCP requests. When you use Light Cat to analyze DHCP traffic, you may notice that some devices are identified as MSFT 50, while others are identified as dhcpcd-5.5.6. This information can help you identify the type of devices connected to your network.
DHCP Name and IP Assignment
The DHCP name assigned to a device is often similar to the device's hostname or computer name. This suggests that the DHCP name is set intentionally by the user or device configuration. Additionally, devices on the same Wi-Fi subnet typically receive IP addresses from the same DHCP server.
Updated Client Vendor Name for Windows Devices
Microsoft has recently updated the traditional Client Vendor Name for some Windows-based devices. The new Client Vendor Name is more descriptive and includes information about the device's make and model. This change helps network administrators and IT professionals better identify and manage Windows devices on their networks.
Conclusion
Understanding the DHCP device type can provide valuable insights into the devices connected to your network. By analyzing DHCP requests using tools like Light Cat, you can identify the type of devices on your network, including Windows computers and Android devices. This information can help you manage your network more effectively and troubleshoot any connectivity issues.
