I have found some tools that seems to update the OUI MAC address vendor database on my system, like get-oui, airodump-ng-oui-update or update-oui :update-oui(8)                          OUI                         update-oui(8)NAME       update-oui - download new version of the OUI and IAB listsSYNOPSIS       update-ouiDESCRIPTION       update-oui  fetches  the  current  version  of the OUI and IAB lists from       http://standards.ieee.org/regauth/oui/index.shtml and installs it, if the       installed versions is older than 5 days.       This utility requires curl, wget or libwww-perl to be installed.OPTIONS       -q     Be quiet. Do not output messages.       -f     Force the update, even if the file is newer than 5 days.FILES       /usr/share/misc/              Directory holding symbolic links to oui.txt and iab.txtBut if I search for IPs on my network:luis@Zarzamoro:~$ sudo netdiscover -i eth1 92 Captured ARP Req/Rep packets, from 12 hosts.

What is the proper command-line way to perform this search?Maybe something like:oui-info 44:d9:e7Note: I know that using the web browser I can google for the MAC's first 3 pairs, but I would like some command-line method, so I could script it or use via remote login (SSH).
Command-line tool to obtain OUI vendor info from MAC address?
mac address
I do not think there is an automated tool to do what you ask, but can be done by working directly on files oui.txt.First of all it identifies the file downloaded, for example: root@kalilloX:~# locate oui.txt/var/lib/ieee-data/oui.txtthen search for the string you are interested. You must remove : or instead insert a -:root@kalilloX:~# grep -i 44d9e7 /var/lib/ieee-data/oui.txt44D9E7     (base 16)        Ubiquiti Networks, Inc.
