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.
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.
Example 14.6. Excerpt from nmap-mac-prefixes
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.
About MAC Address Lookup Tool
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 mac address, moreover it tells us what country was this device manufactured. Free chroma key software. All this information is useful if you want to verify the generated mac address with the original vendor of this device in OUI vendor database.
What is a MAC Address?
MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits.
The network adapters or network interface cards always come with a MAC address which is fed into hardware, usually in read-only memory (ROM), or BIOS system. The physical address is stored into the NIC by its manufacturer, that is why this address is also called a burned-in address (BIA) or ethernet hardware address.

There are several NIC manufacturers; some well-known of them are Dell, Cisco, Belkin. The first three sets of two hexadecimal numbers in a MAC Address identifies the card manufacturer, and this number is called OUI (organizationally unique identifier). OUI is always the same for NICs manufactured by the same company. For example, let's say a network card manufactured by dell has a physical address:
00-14-22-04-25-37 , in this address, 00-14-22 is the OUI of Dell which identifies that the device is by Dell. It may be interesting for you to know that all the OUIs are registered and assigned to the manufacturers by IEEE.
