Windows and Android Device Identification in DHCP Requests

Introduction

DHCP (Dynamic Host Configuration Protocol) is a network protocol that assigns IP addresses and other network configuration to devices connected to a network. When a device requests an IP address from a DHCP server, it includes a vendor class identifier in the request. This identifier helps the server determine the type of device requesting the IP address and apply the appropriate settings.

Windows and Android Device Identifiers

In the case of Windows and Android devices, the vendor class identifiers are: * WEB MSFT 5 0 for Windows computers * dhcpcd-5 5 6 for Android devices These identifiers are used by the DHCP server to identify the type of device requesting the IP address and assign the appropriate settings.

Light Cat Device

In the example provided, a device with the vendor class identifier WEB MSFT 5 0 is requesting an IP address. This identifier indicates that the device is a Windows computer. The device is also on the same Wi-Fi subnet as the DHCP server, and its DHCP name is similar to the PC name, suggesting that it is an intentional device.

Updated Client Vendor Name

Traditionally, the Client Vendor Name for some Windows-based devices was simply MSFT 5 0. However, this value has been updated to include additional information. When examining the DHCP process between devices and the Wi-Fi router DHCP server with Wireshark, it is noticeable that most devices provide a more detailed Client Vendor Name that includes the device model and manufacturer.

Conclusion

The vendor class identifier in the DHCP request is used to identify the type of device requesting the IP address. In the case of Windows and Android devices, the identifiers are WEB MSFT 5 0 and dhcpcd-5 5 6, respectively. These identifiers help the DHCP server to assign the appropriate IP address and network settings to the device.
