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.
