It is a unique identifier for network interfaces. It is used as a network address for most IEEE 802 network technologies. Sometimes it is known as the burned-in address (BIA) or the Ethernet hardware address (EHA). Among its applications are the Ethernet, 802.11 wireless networks and Bluetooth.<\/p>\r\n<p><img class=\"aligncenter size-full\" src=\"\/howto\/wp-content\/uploads\/2018\/04\/what-is-mac-address.jpg\" alt=\"what is mac address\" width=\"720\" height=\"453\" \/><\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"what_is_a_mac_address\"><\/span><b>What Is A MAC Address?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>The <a href=\"https:\/\/en.wikipedia.org\/wiki\/MAC_address\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">MAC address<\/a> is usually assigned by the manufacturer of a Network Interface Controller (NIC), and it is stored in the hardware. The NIC is a computer circuit card that allows a computer to connect to a network. During network communication the Address Resolution Protocol (ARP) for the Internet Protocol Version 4 (IPv4) or the Neighbor Discovery Protocol (NDP) for IPv6 translates the IP into a NIC.<\/p>\r\n<p>The MAC address is formed in accordance to the rules of the three numbering name spaces, which are managed by the Institute of Electrical and Electronic Engineers (IEEE). The format is six sets of two digits or characters, separated by hyphens. An example of a MAC address is 30-65-EC-6F-C4-58.<\/p>\r\n<p>Some manufacturers, such as Dell, place a unique identifier in the MAC address, which is called the Organizationally Unique Identifier (OUI), and identifies the manufacturer. The OUIs of some well-known firms are:<\/p>\r\n<ul>\r\n\t<li>Dell: 00-14-22,<\/li>\r\n\t<li>Cisco: 00-40-96,<\/li>\r\n\t<li>Nortel: 00-04-DC.<\/li>\r\n<\/ul>\r\n<p>Some firms may have more than one MAC address.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"what_is_a_mac_address_used_for\"><\/span><b>What Is A MAC Address Used For?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>One of the applications of MAC addresses is in the filtering process on wireless networks. In order to prevent strangers from accessing a network, the router is set to accept only specific MAC addresses. In this manner, if the IP address changes, as for example in the case of dynamic IP addresses, the MAC address can still identify the device.<\/p>\r\n<p>Filtering can be used to track network users, and to limit their access. It can also have other uses, such as identifying when a stolen device connects to the network. For these reasons, many companies and institutions require the MAC addresses of their members\u2019 devices. Therefore, it is important for device owners not to reveal their MAC addresses to anyone, except to authorized\u00a0personnel.<\/p>\r\n<p>MAC addresses can also be used in data recovery to connect to a wireless device. Disk Drill is an app, developed by Cleverfiles, which helps in data recovery. It searches for lost files by scanning in two possible modes, namely Quick and Deep Scan. Quick Scan uses the metadata still available in the file system. Deep Scan drills deeper into the binary level. The results are presented with the help of a filter.<\/p>\r\n<p>Disk Drill is available for Windows and Mac computers, and can be download for free.<\/p>\r\n<div class=\"relative bottom download__block\">\r\n            <div class=\"d-flex align-center download__block__inner\">\r\n                <div class=\"download__block__image-wrapper\">\r\n                <div class=\"download__block__image\">\r\n                    <img src=\"\/howto\/wp-content\/uploads\/2020\/03\/sidebar-ban-96.png\" srcset=\"\/howto\/wp-content\/uploads\/2020\/03\/sidebar-ban-2x-1.png 2x\" alt=\"Disk Drill\" width=\"96\" height=\"96\">        \r\n                <\/div>\r\n                <\/div>\r\n                <div class=\"download__block__announce\">\r\n                    <b>download-block-title<\/b><br>\r\n                    download-block-text\r\n                <\/div>\r\n                <div class=\"download__block__action\">\r\n                    <a href=\"\/\/download.html\" data-href-mac=\/\/disk-drill-mac.html data-href-win=\/\/disk-drill-win.html class=\"button button-green btn-md osreplace\">\r\n<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n<path d=\"M11.9546 7.293C11.8736 7.114 11.6956 7 11.4996 7H9.49957V0.5C9.49957 0.224 9.27557 0 8.99957 0H6.99957C6.72357 0 6.49957 0.224 6.49957 0.5V7H4.49957C4.30357 7 4.12557 7.115 4.04457 7.293C3.96257 7.472 3.99457 7.681 4.12357 7.829L7.62357 11.829C7.71857 11.938 7.85557 12 7.99957 12C8.14357 12 8.28057 11.937 8.37557 11.829L11.8756 7.829C12.0056 7.682 12.0356 7.472 11.9546 7.293Z\" fill=\"white\"\/>\r\n<path d=\"M13.5 11V14H2.5V11H0.5V15C0.5 15.553 0.948 16 1.5 16H14.5C15.053 16 15.5 15.553 15.5 15V11H13.5Z\" fill=\"white\"\/>\r\n<\/svg>\r\ndownload-block-button-text\r\n<\/a>\r\n                <\/div>\r\n            <\/div>\r\n        <\/div>\r\n<p><img class=\"aligncenter size-full\" src=\"\/howto\/wp-content\/uploads\/2017\/02\/ddMacComicsPromo.jpg\" alt=\"Disk Drill\" width=\"640\" height=\"526\" \/><\/p>\r\n<p>MAC addresses are also necessary for a MAC address lookup, which means finding the geographical location of the device via the MAC address.<\/p>\r\n<p>For the purpose of connecting to a device, and recovering its data, or setting up a filtering process, or looking up the location.

A set of labels and values will appear. The MAC address is listed under the description of Physical Address.<\/p>\r\n<p>In a Mac computer, the process to find MAC address is as follows: go to utilities, (Finder \u00e0 Utilities or Command + Shift + u) and start the Terminal app. Type <i>networksetup \u2013listallhardwareports. <\/i>The computer will display all network interfaces and their MAC addresses (Ethernet Addresses).<\/p>\r\n<p>In an iPhone, to find MAC address select in the home menu: Settings \u00e0 General \u00e0 About.
