MSFT 5.0 and dhcpcd-5.5.6: Vendor Class Identifiers in DHCP Requests

Unveiling the DHCP Name Similarity to PC Name: Intentional or Coincidental?

Device Fingerprinting and Client Identity in Router Configurations

MSFT 5.0, commonly associated with Windows computers, and dhcpcd-5.5.6, typically found on Android devices, are vendor class identifiers present in DHCP requests. These identifiers provide insights into the type of device making the request.

When encountering login pages, splash pages, or ISP router pages, Microsoft's detection test may fail. However, the DHCP name often closely resembles the PC name, suggesting a deliberate action.

Network administrators can configure device fingerprinting and client identity settings within their routers. Under "Security" and "Device Fingerprinting," they can create predefined settings for Windows, Android, and iOS devices.

In conclusion, the vendor class identifiers in DHCP requests, coupled with the similarity between DHCP names and PC names, provide valuable information in network troubleshooting and device fingerprinting. Understanding these concepts empowers network engineers and administrators to optimize network configurations and ensure seamless connectivity.
