For many consumers, privacy is increasingly a negligible issue. “Okay, so what’s the big deal?” you may be thinking. And whether you are using ethernet (LAN) networks, WiFi signals, or even Bluetooth, chances are that any device you buy from now on will have a unique EUI-64 code(s). So, just as IPv6 was launched for IP addresses, we now have 64-bit MAC addresses for computer networking hardware. Similar with IPv4 – the original version of IP addresses – MAC addresses assigned at the 48-bit level are predicted to run out by the year 2100. Another convention used by networking equipment uses three groups of four hexadecimal digits separated by dots (.) (e.g. This form is also commonly used for EUI-64. The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (-) or colons (:), in transmission order (e.g. The IEEE claims trademarks on the names EUI-48 and EUI-64, in which EUI is an abbreviation for Extended Unique Identifier. MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64. Here’s a quick rundown for nerds in the room: That is why they are often called a burned-in address (BIA), an ethernet hardware address (EHA), or simply a “physical” address, because they are literally assigned and stamped into your network card by whichever company manufactured your hardware. While IP addresses are dynamic, ever-changing numbers temporarily assigned to your home or computer by an internet service provider (ISP), a MAC address is a permanent ID number used to identify a device’s network interface card (NIC).ĭid you catch that? While IP addresses change often, MAC addresses don’t ever change.
