Unveiling the Mystery of Device Types in DHCP: WEB MSFT 5 0, DHCPCD-5 5 6, and More

Light Cat in DHCP

Have you ever wondered why your Wi-Fi router assigns different device types in the DHCP (Dynamic Host Configuration Protocol) request? One such device type that has piqued interest is "WEB MSFT 5 0." This enigmatic identifier represents a Windows computer, while "dhcpcd-5 5 6" is associated with an Android device. However, a deeper dive into Wireshark analysis revealed a surprising update: the traditional "MSFT 50" Client Vendor Name has been updated for some Windows-based devices.

Exploring the DHCP Process

To understand the role of "WEB MSFT 5 0" in the DHCP process, let's explore the steps involved:

1. A client device (e.g., Windows computer, Android device) sends a DHCP discover message to the network to obtain an IP address.
2. The message includes various parameters, such as the vendor class identifier ("WEB MSFT 5 0" or "dhcpcd-5 5 6").
3. The DHCP server responds with a DHCP offer, proposing an IP address and other network configuration parameters to the requesting device.
4. The client device accepts the offer and sends a DHCP request to confirm the IP address assignment.
5. The DHCP server acknowledges the request and provides the client with the assigned IP address and other network settings.

As you can see, the device type indicated in the DHCP request helps the DHCP server identify the type of device and assign appropriate network settings.
