Vendor Class Identifiers (VCIs) for Different Devices

Different Devices, Different VCIs

When a device connects to a DHCP server, it sends a request that includes a vendor class identifier (VCI). This VCI tells the server what type of device it is.

VCI for Windows Devices

The VCI for Microsoft Windows 10 devices is MSFT 50. This VCI has been used by Windows devices for many years and is the most common VCI for Windows devices on networks.

VCI for Android Devices

The VCI for Android devices is dhcpcd-5.5.6. This VCI is used by Android devices to identify themselves to DHCP servers. It is a relatively new VCI, as Android devices have only been on the market for a few years.

Importance of VCIs

VCIs are important because they allow DHCP servers to provide the correct configuration information to devices. For example, a DHCP server may provide a different IP address range to Windows devices than it does to Android devices.

Troubleshooting DHCP Request Vendor Class Identifier Test Failure

If you are attempting to perform the DHCP request vendor class identifier test and you encounter a failure, it may be because you are on a network that is not configured to support VCIs. You can contact your network administrator to see if this is the case.
