module to look up the vendor by OUI
The Institute of Electrical and Electronics Engineers (IEEE) assigns an Organizational Unique Identifier (OUI) to manufacturers of network interfaces. Each interface has a Media Access Control (MAC) address of six bytes. The first three bytes are the OUI. . Net::MAC::Vendor allows you to take a MAC address and turn it into the OUI and vendor information. You can, for instance, scan a network, collect MAC addresses, and turn those addresses into vendors. With vendor information, you can often guess at what you are looking at (e.g. an Apple product). . You can use this as a module as its individual functions, or call it as a script with a list of MAC addresses as arguments. The module can figure it out.
