What is MAC Address
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies and most IEEE 802 network technologies including Ethernet. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.
MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card’s read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number
MAC Address Conventions
The first half of a MAC address contains the ID number of the adapter manufacturer. These IDs are regulated by an Internet standards body (see sidebar). The second half of a MAC address represents the serial number assigned to the adapter by the manufacturer.
In the example,
indicates the manufacturer is Intel Corporation.
MACAddressView – A Freeware Tool to Find MAC Address Vendor and LookUp
MACAddressView enables you to look up the company name, address and country that is registered to the MAC address of a product (e.g. routers, computers and other network devices). You can also look up MAC address ranges by company name, address or country name. The program uses an internal database for MAC address lookups and does not require an Internet connection. MACAddressView can come handy if your router or network scanner displays MAC addresses that you don’t recognize.
How To Find MAC Address Vendor, Country and Other Details Using MACAddressView
MACAddressView doesn’t require any installation process or additional DLL files. In order to start using it, simply copy the executable file (MACAddressView.exe) to any folder you like, and run it.
After running MACAddressView, the ‘Find MAC Address Records’ will appear. By default, the ‘Find By’ option is set to ‘MAC Address’. In this mode, you can type one or more MAC Addresses, separated by space, comma, or Enter key. You can try a full MAC address (like 01-02-03-04-05-06) or only the first 3 bytes of the address (like 01-02-03). After typing all MAC Addresses you need, click the ‘Ok’ button to view the details of all MAC records that you asked.
You can also locate a MAC record according to the company name, company address, or country name. You can look in the examples below to find out what you can do with these options.
