MAC address vendor lookup

Utilizing our MAC addresses checker, when you provide a MAC address/OUI/IAB, you can delve into OUI vendor specifics, pinpoint virtual machines, identify manufacturer locales, interpret the data within the MAC, and access our comprehensive findings on any MAC address, OUI, IAB, or IEEE through our MAC addresses lookup.

What is a MAC address?

A device’s MAC address (Media Access Control address) is a unique sequence of numbers assigned to a network interface controller. It’s an identifier communicating at the data link layer of a specific network segment. For the majority of IEEE 802 network technologies, including Ethernet and Wi-Fi, MAC addresses function as network addresses. Thus, MAC addresses will be used in one of the sublayers of the medium access control protocol
  • A network node may have a few network interface controllers (NICs), and each of them will have its own unique MAC address. More sophisticated network devices such as routers and multilayer switches could even require several permanent MAC addresses

  • The manufacturer of a network interface controller (NIC) assigns MAC addresses that are stored in its hardware, such as a card's read-only memory or other firmware. In that event, a MAC address usually encodes the manufacturer's registered identification number and could be called the burned-in address (BIA). It may also be referred to as an EHA (Ethernet hardware address), hardware address or physical address, unlike a programmed address, in which the host device issues commands to the NIC so as to use an arbitrary address

  • The original IEEE 802 MAC address is derived from the original Xerox Ethernet addressing scheme. This 48-bit address space potentially contains 2^248 or 281,474,976,710,656 possible MAC addresses.

  • MAC address history

    MAC addresses were introduced in the 1980s as part of the Ethernet standard. Since then, they have become an integral part of any network infrastructure. At a time when the Internet was just beginning its development, MAC addresses played a key role in identifying devices on a local area network.

    With the development of wireless technology and the increasing number of connected devices, the importance of MAC addresses has only increased. They not only help with identification, but also with security, allowing network administrators to control access to the network.

    Today, in the age of the Internet of Things (IoT), every device, from smartwatches to refrigerators, has its own unique MAC address. This emphasizes their importance in today's world.

    How could I get MAC address of my website visitor?

    A host cannot determine from the MAC address of another host whether that host is on the same link (network segment) as the sending host, or it is on a network segment bridged to that network segment.
  • MAC is short for Media Access Control, where media refers to the local transmission media. A MAC address is not broadcast beyond the LAN of the device it is connected to, as it is locked in the internal network. Whereas source and destination IP-Addresses remain the same and are therefore used for long-distance routing decisions, the source and destination MAC addresses will indicate the next hop.

  • The MAC address stored in the packet changes on every hop of its journey. Due to that, the MAC address stored in the packets which are received by your server will be the MAC address of your point of presence’s router or the equipment of your ISP.

  • The only way to get the visitor's MAC address is to run code on his laptop, from the browser. There is no way to do it since it would be a breach of privacy or security.

  • There are several workarounds like running Active-X controls for Internet Explorer only or running XPCOM for Mozilla Firefox only. But these approaches require extension installation or a prompt from the user, so they wouldn't work for collecting all the visitors’ MAC addresses in background.
  • How to use Mac Checker?

    Enter the MAC address whose information you want to know in the input box and click "check" to get the device information. Typically, the MAC address is in the form: XX:XX:XX:XX:XX:XX:XX:XX:XX, where X is numbers or letters from A to F.
