DHCP Vendor Identifiers for Windows and Android Devices

Updated Vendor Class Identifiers

A significant update has been made to the DHCP Vendor Class Identifiers for Windows and Android devices. These updates have a direct impact on network management and device identification within DHCPv4 environments.

Windows Devices

For Windows devices, the traditional Client Vendor Name "MSFT 50" has been updated. Some devices will now show up as "MSFT 50.0" in DHCP request messages.

Android Devices

Android devices have also received an update to their DHCP Vendor Class Identifier. The new identifier for Android devices running dhcpcd-5.5.6 is "WEB dhcpcd-5.5.6".

Option 60 Value Mapping

The following table provides a mapping of the new Vendor Class Identifiers to their corresponding Option 60 values:

Vendor Class Identifier	Option 60 Value
WEB MSFT 5 0	MSFT 50
WEB dhcpcd-5 5 6	dhcpcd-556

DHCP Server Configuration

To ensure compatibility with the updated Vendor Class Identifiers, DHCPv4 servers should be configured to send Vendor-specific Options to clients. This configuration enables the DHCPv4 client to receive and process the new identifiers.

Conclusion

These updates to the DHCP Vendor Class Identifiers for Windows and Android devices are crucial for accurate device identification and network management. By understanding these updates, network administrators can ensure that their DHCPv4 servers are properly configured to handle the latest devices and provide seamless network connectivity.
