DHCP Vendor Class Identifier: WEB MSFT 5 0 vs dhcpcd-5 5 6
Subtle Differences Between Devices
When analyzing DHCP requests using Wireshark, it's evident that different devices utilize varying Vendor Class Identifiers (VCIs). WEB MSFT 5 0 is commonly associated with Windows computers, while dhcpcd-5 5 6 is typically seen in Android devices. These VCIs allow DHCP servers to tailor their responses based on the device type, providing optimized configurations for each.
New DHCP Client Features in Windows 10
With the release of the Windows 10 April 2018 Update, the DHCP client received several enhancements. One notable addition is the ability for administrators to configure DHCPv4 servers to transmit Vendor-specific Options to specific clients. This feature enables more granular control over DHCP responses, allowing for customized configurations based on vendor class.
Significance of Vendor Class in DHCP Option 43
DHCP Option 43, also referred to as Vendor Specific Information, is a crucial component in the DHCP process. As mentioned earlier, the value of this option is only sent to clients with a specific vendor class. For instance, in the case of WEB MSFT 5 0, DHCP Option 43 data is only transmitted to devices that have this VCI. This ensures that the provided information is relevant to the specific device and not generic.
