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-iab.txt. It is for MAC-vendor mappings that are not covered by the IEEE manufacturer
Each line in the
mac-vendor.txt file contains a MAC-vendor mapping in the form:
Where <MAC-Prefix> is the prefix of the MAC address in hex, and <Vendor>
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.
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 attempt to match larger prefixes before trying to match smaller ones, and
will stop at the first match.
