MAC Address Lookup: An Ultimate Guide with 3 Surprising MAC Address Uses 

Working in the computing world opens doors to multiple systems that require your utmost attention to understand better. Similarly, learning network systems is a basic or fundamental aspect of defining the process of machines communication. 

For this purpose, you might have already known about the IP address (Internet Protocol)-it’s a specific address used over the internet or local networks to identify the respective devices. 

However, for your private networking (either wired or wireless), a MAC address (also known as Media Access Control Address) ensures the transfer of information to the right device. The manufacturing companies embed the MAC Address within the devices (compatible with the internet).

Let’s dive deep to get more insights about MAC Address Lookup…

MAC Address: A Quick Overview  

Due to a huge amount of (network-based) devices around the globe, MAC address is an easy way to identify devices. Consequently, the MAC address is a unique number set that defines each device connected to your respective network. 

Associated with NIC (Network Interface Controller) MAC address is the Physical Address of the network device. 

Therefore, after connecting the devices to your private or local network via WIFI signal or Ethernet cable, the MAC address transfers specified data to the particular devices. 

Now let’s see the number format of the MAC address… 

Structure and Format of MAC Address 

It is a 48-bits address based on 12 digits. All the values are in hexadecimal order, divided into 6-byte binary numbers. These hexadecimal numbers are separated with colon, period, or hyphen, depending on the device’s manufacturer. 

Examples;

Notation Types Company
Period

0A07.5F3B.4F23

Cisco
Colon

0A:07:5F:3B:4F:23

Linux/Mobile/Apple
Hyphen

0A-07-5F-3B-4F-23

Microsoft

 

Moreover, IEEE Registration Authority Committee provides these 6-byte sets to the particular brand, which represent two major things;

  1. Organizational Unique Identifier: 

OUI is also called a company code that remains the same for every device (a company produces). In other words, the first three bits are OUI, which contains the company or brand name. 

  1. Universal Administered Address: 

UAA is the last three bits in the MAC Address, and IEEE allows the company to change it according to their requirements.  

Example;

Organizational Unique Identifier Universal Administered Address
0A 07 5F 3B 4F 23

 

Types of MAC Address 

It helps in local networking communication, and thus it is divided on the basis of the number of communicating sources. 

  • When a respective machine shares information with a single source, it’s a Unicast. And thus, the latter device’s MAC Address will be unicast. 
  • Transferring information or commands between two or more groups within the local networking communication refers to a multicast address. 
  • Within the local network communication, the sharing of information with all the connected devices is known as the broadcast address.

You might be thinking about the surprising uses of the MAC Address, right? So, there you go…

3 Major Uses of MAC Address 

It is found in the network device memory that doesn’t require any configuration. And your computer gets the particular MAC Address automatically. Still, most operating systems permit MAC Address changes. 

Despite governing local network communication, MAC Address is; 

  • Used to identify device details. For instance, by knowing the first three 8-bit sets, you can get information about the device manufacturer. 
  • MAC Address spoofing (changing or stealing the previous MAC Address) might not sound legal, but it helps high authorities to identify insecure systems and take relevant actions. 
  • It can also be used to track down the location of lost devices. Despite multiple IP addresses, MAC Address remains unchanged and helps identify the device location. 

MAC Address Lookup Tool: All you need to know 

After a comprehensive discussion on MAC address, its types, and uses, you can also identify the MAC address of any networking card using the MAC Address Lookup tool. This tool helps you find the information related to the MAC address installed in your computer, laptop, mobile, or other internet-compatible devices. 

Steps to Use MAC Address Lookup Tool

MAC Address can be found on the network card box. Consequently, you can try the following steps to get your MAC Address Lookup information. 

  1. No matter what windows version you are using, you need to type ipconfig /all in the command prompt and press Enter to get your installed MAC address.

         2. Afterward, you can find the MAC Address located on the network card from the physical address option. 

      3. Copy the Address and paste it into the dialog box. 

      4. Click the Search button. 

 

      5. The final product will look somewhat like this; 

Wrapping up 

Hopefully, you’d understand all the basic concepts about the MAC Address. It’s a unique combination of hexadecimal numbers that distinguish every device. And helps the local networking system send relevant information to the devices.
