This IP reservation feature is quite helpful for advanced network applications.Ĭonversely, you can also use MAC to deny (or explicitly allow) access to an adapter via MAC filtering, a kind of a security feature. When this happens within the network, the device will get the same IP address each time it connects. You can also use the MAC to reserve a particular IP address for an adapter within a local network. Without an IP address, the device can’t connect at all. Without MAC, an adapter can’t get an IP address. The use of a MAC addressĪ DHCP server (like your router) uses a MAC address to assign an IP address to a network adapter. IP Reservation is one of many uses of the MAC address.

Specifically, you can’t register your vehicle (and get a new license plate) if it doesn’t have a VIN. Both are used to identify a car but at different levels and purposes. If MAC is the VIN of a car, then the IP address is the license plate.

Once the device is yours, however, it’s a good idea to keep this address secure. It’s not a secret everyone can see it - again, it’s like the VIN of a car, it must be visible. Generally, a device has its MAC on its label.

Here are a few examples: Physical address, basic service set identifier (BSSID), Ethernet hardware address (EHA), hardware address, and adapter address.

There are many other names for a MAC address.

But considering this is a 48-bit scheme with a total of 281,474,976,710,656 - that’s 281 trillion and then some hundred billion more - possible addresses, it’s safe to say many things more consequential, like humanity or hopefully just the need for the MAC itself, would expire before we have to worry about a MAC shortage.

Eventually, we’ll run out of MAC addressing space.

Take “permanent” with a grain of salt because, just like a VIN, it’s susceptible to modification.

It’s like the vehicle identification number (VIN) of a car. It’s embedded in each networking adapter by the manufacturer. Here are some interesting facts about the MAC address. Generally, each time you appropriately alter a digit or a letter, you’ll get a new MAC. This same address can also appear as d4:fb:6a:7c:31:b4 or D4FB6A7C31B4, depending on what platform or application you use to view it.Īs you might have noticed, MAC is not case-sensitive, but it tends to appear either all lower case or all upper case. If it belongs to an actual device, that’s just a coincidence.) (This is a random address I made up for this post.

That said, here is a MAC address as you’d see on a Windows computer: Depending on where you view the address, these groups are separated by colons, hyphens, or nothing at all. This NIC comes as a Wi-Fi adapter, an Ethernet adapter (wired), or a cellular modem.Ī MAC address consists of six groups of two characters (numbers or letters). Your device - be it a computer, a tablet, or a phone - can connect to the Internet because it has a NIC. So a MAC address - I’ll call it MAC from now on for short - is precisely that, the unique identifier to control the access of a network interface controller (NIC), which we often call a network adapter.
