Users rarely modify this file, which maps MAC address prefixesto vendor names. Read on for the complete treatment.

Ethernet devices, which have become the dominant networkinterface type, are each programmed with a unique 48-bit identifierknown as a MAC address.This address is placed in ethernet headers toidentify which machine on a local network sent a packet, and whichmachine the packet is destined for. Humans usually represent it as ahex string, such as 00:60:1D:38:32:90. Minecraft death beacon mod.

OUI is an IEEE Registration Authority (RA) specific term that is referred to in various standards and may be used to identify companies on the IEEE Public Listing. A MA-L assignment includes an OUI and the right to generate various extended identifiers based on that OUI. It is most often used to create IEEE 802-defined MAC addresses (EUI-48. MAC Address Lookup Tool searches your MAC Address or OUI in mac address vendor database. The MAC Address vendor database consists of a list of mac addresses of all devices manufactured till date. Finding the mac address from this database tells us which manufacturer originally manufactured this device and what is the prefix, postfix of a given. Control Center for Mac. Instantly access the controls you use most — like Wi-Fi and Bluetooth — and new controls to play music and enable Dark Mode for your display. Designed just for Mac, the new Control Center lets you add controls and drag favorites to the menu bar to customize it just for you.

To assure that MAC addresses are unique in a world withthousands of vendors, the IEEE assigns an Organizationally UniqueIdentifier (OUI)to each company manufacturing ethernet devices. Thecompany must use its own OUI for the first three bytes of MACaddresses for equipment it produces. For example, the OUI of 00:60:1D:38:32:90is 00601D. It can choose the remainingthree bytes however it wishes, as long as they are unique. A counter is thesimple approach. Companies that assign all 16.8 million possible valuescan obtain more OUIs.nmap-mac-prefixes maps each assigned OUI to thename of the vendor that sells them.Example 14.6is a typical excerpt.

The first value is the three-byte OUI as 6 hex digits. It isfollowed by the company name. This file is created from the complete list athttp://standards.ieee.org/regauth/oui/oui.txtby transforming it with a simple Perl script.The IEEEalso offers an OUI FAQ at http://standards.ieee.org/faqs/OUI.html.

Nmap can determine the MAC address of hosts on a local ethernetLAN by reading the headers off the wire. It uses this table to lookup and report the manufacturer name based on the OUI. This can beuseful for roughly identifying the type of machine you are dealingwith. A device with a Cisco, Hewlett Packard, or Sun OUI probablyidentifies a router, printer, or SPARCstation, respectively. Example 14.6, “Excerpt from nmap-mac-prefixes” shows that the deviceat 00:60:1D:38:32:90 was made by Lucent. It is infact the Lucent Orinoco wireless card in my laptop.
