How to Purchase CommView for WiFi

NIC Vendor Identifier

The first 24 bits of a network card's MAC address uniquely identify the network card's vendor. This 24-bit number is called the OUI ("Organizationally Unique Identifier").  The NIC Vendor Identifier is a tool that allows you to look up a vendor name by MAC address. To look up a vendor name, click Tools =>NIC Vendor Identifier, enter a MAC address, and click Find. The vendor's name will be displayed. By default, CommView replaces the first three octets of the MAC address by the adapter vendor name in the Packets tab. This behavior may be changed by unchecking the Display vendor names in MAC addresses checkbox in the General tab of the program Options dialog.  The list of vendors is contained in the MACS.TXT file located in the CommView application folder. You can manually edit this list to add/modify information.
