Understanding Device Types from DHCP Vendor Class Identifiers

WEB MSFT 5.0 vs. dhcpcd-5.5.6: Identifying Device Types

Introduction

When analyzing DHCP (Dynamic Host Configuration Protocol) requests using Wireshark, you may encounter vendor class identifiers that indicate the type of device sending the request. Two common identifiers are WEB MSFT 5.0 and dhcpcd-5.5.6, which typically represent Windows computers and Android devices, respectively.

DHCP Vendor Class Identifier Explained

The vendor class identifier is a field within the DHCP request that allows a device to advertise its type to a DHCP server. This information helps the server assign appropriate IP address settings and other configuration parameters based on the device's capabilities.

Why "light cat MSFT 5.0" is Displayed for Windows Devices

In some cases, you may observe "light cat MSFT 5.0" being displayed in network monitoring tools when capturing DHCP requests from Windows devices. This is because Microsoft has updated the traditional Client Vendor Name for Windows-based devices, which used to be simply "MSFT 5.0".

The IP Assignment Process

The DHCP assignment process essentially assigns an IP address and related parameters to a device based on its DHCP request. The device type indicated by the vendor class identifier helps determine the specific settings applied to the device.

Implications for Device Management

Understanding device types from DHCP vendor class identifiers can be beneficial for network administrators and IT professionals. By identifying the type of device connected to a network, you can better optimize network resources, implement appropriate security measures, and troubleshoot any connectivity issues.
