MAC-VENDOR(5)		      File Formats Manual		 MAC-VENDOR(5)

NAME
       mac-vendor - Ethernet vendor file for arp-scan

SYNOPSIS
       mac-vendor.txt

DESCRIPTION
       The  mac-vendor.txt contains Ethernet MAC to vendor string mappings for
       arp-scan.  It is	used in	addition to the	IEEE OUI and IAB  listings  in
       ieee-oui.txt  and ieee-iab.txt.	It is for MAC-vendor mappings that are
       not covered by the IEEE manufacturer listings.

       Each line in the	mac-vendor.txt file contains a MAC-vendor  mapping  in
       the form:

       <MAC-Prefix><TAB><Vendor>

       Where  <MAC-Prefix>  is the prefix of the MAC address in	hex, and <Ven-
       dor> is the name	of the vendor.	The prefix can be of any  length  from
       two hex digits (one octet) to twelve hex	digits (six octets, the	entire
       Ethernet	hardware address).  The	alphabetic hex characters  [A-F]  must
       be entered in upper case.

       For example:
       012345	 would match 01:23:45:xx:xx:xx,	where xx represents any	value;
       0123456	 would match 01:23:45:6x:xx:xx;	and
       01234567	 would match 01:23:45:67:xx:xx.

       Blank lines and lines beginning with "#"	are ignored.

       The  order  of entries in the file is not important.  arp-scan will at-
       tempt to	match larger prefixes before trying to match smaller ones, and
       will stop at the	first match.
