DHCP Based on MAC OUI
Description of the Router App
Caution
- This Router App has been tested on a router with firmware version 6.3.10. After updating the router firmware to a higher version, check whether a newer version of the Router App has also been released and update it accordingly for compatibility.
The DHCP Based on MAC OUI Router App handles IP address assignment for devices according to their MAC OUI.
Tips
For the DHCP Based on MAC OUI Router App to work, you must disable the router's own DHCP protocol.
What is MAC OUI?
The MAC OUI (Organizationally Unique Identifier) is the first 24 bits (first 3 octets) of a MAC address that identifies the manufacturer of the network device. The IEEE assigns these unique OUI identifiers to companies that need to include them in their networking products.
By looking up the OUI portion of a MAC address, you can determine the manufacturer of the device. This information can be useful for network configuration, troubleshooting, and security profiling. For example, you could use the OUI to identify the vendor of devices on your network and apply appropriate security policies.
The remaining 24 bits (last 3 octets) of the 48-bit MAC address are assigned by the manufacturer to uniquely identify each individual network interface card (NIC). So the full MAC address provides both the manufacturer information (OUI) and a unique identifier for that specific device.
Web Interface
Once the installation is complete, access the Router App's web interface by clicking the Router App name on the Router Apps page of the router's web interface.
The left panel of the web interface contains a menu with a Status section and an Administration section. The Administration section contains only the Return item, which switches back to the router's web configuration pages. The main menu is shown in the figure below.
Configuration
Global
Configure all DHCP Based on MAC OUI Router App settings by clicking the Global item in the main menu.
