MAC Address Generator

Introducing Our Online MAC Address Generator

Our MAC address generator online helps you create random MAC addresses for testing purposes. You can generate MAC addresses in bulk as sample data to imitate devices and computers when testing applications or online tools.

What Exactly is a MAC Address, and Why Should You Generate One?

A MAC address is a unique combination of numbers and alphabets assigned to network devices. If ten devices are on a network, they will all have a unique MAC address that distinguishes them from one other.

There are different reasons for generating a MAC address. For example,

• You can use it to learn what MAC addresses look like. You can learn their format and appearance so that you can easily find your own devices when the need arises.
• A MAC address can also be generated for testing purposes. In other words, if you are developing an app or website that requires sample data involving computer names and their MAC addresses, you can use our tool to generate the latter type of data.

A Guide to Using Our MAC Address Generator

Below, we have listed the steps required to use our Mac address generator.

• To get started, open the tool at this URL: https://dnschecker.org/mac-address-generator.php
• Once the tool is open, enter your required MAC address prefix. This step is optional. However, you can use it if you are looking for a certain MAC address range or type.
• Then, click on the drop-down menu to choose the MAC address format. This decides the format/appearance in which the generated addresses will appear.
• Then, select if the alphabet in the MAC address should be in UPPERCASE or lowercase. The default selection will be in UPPERCASE.
• Finally, select the “Limit,” which will decide the number of MAC addresses to be generated per click.

Click on the “Generate MAC Address” button to start the process.

Copy or Download MAC Addresses Directly to Your Device

Once the process is complete and our Mac generator tool has provided you with the MAC addresses (according to the adjusted settings/options), you can perform the following steps:

• You can click on any MAC address from the list to copy it to your clipboard. You can simply click on any address using your mouse cursor (or tapping your finger on a mobile device), which will be copied.
• To download the MAC address(es) to your device, click the “Download Data” button. You will be given the option to download the addresses to your device in CSV or JSON format.

What are the Different MAC Address Formats, and Why Do They Matter?

You can choose from four different MAC address formats when generating them with our tool. The formats include:

• 00-10-FA-63-38-4A
• 10.FA.63.38.4A
• 00:10:FA:63:38:4A
• 0010FA63384A

In the first format, the octets in the address are separated by hyphens.

In the second format, the octets are separated using a period.

In the third format, the octets are separated using a colon.

In the fourth format, there is no separation whatsoever.

The format of the MAC addresses depends on how the data is required by the system in which you provide the addresses.

For example, if you are using the generated addresses for testing purposes, the software or the application in question may require the addresses to have no separating elements inside. In such a case, you can specify this format before clicking on the “Generate” button.

Note: It is important to remember that the MAC addresses generated by our tool are not real. They don’t belong to actual devices. They won't return any details if you wish to validate them using a MAC address validator. MAC address validators, such as the one we provide here on our platform, are meant to work with actual MAC addresses, not dummy ones.

What is an OUI in a MAC Address?

OUI stands for Organizationally Unique Identifier. It refers to the first three sets in the MAC address, i.e., the first six digits.

The OUI is unique to the manufacturer of the network interface cards. All the MAC addresses issued by that particular manufacturer will share the OUI, while the rest of the digits will be random.

FAQs

What is the purpose of a MAC address?

The purpose of the MAC address is to identify devices on a network. The MAC address of each device on a network, be it a phone or a PC, is different from the other.

How do I find the MAC address of my own device?

On a Windows device, you can open the command prompt and use the command “ipconfig /all” without the quotes. The MAC address will be listed as the physical address. On a Mac device, however, you can click on the Apple logo and then follow this path: System Preferences > Ethernet > Advanced > Hardware. The MAC address will be listed here.

Does the format matter a lot in the MAC address?

No, the format does not matter in the MAC address. Whether the pairs are separated by a period, a colon, or a hyphen doesn’t matter. However, it is important to create the MAC address in the format that is requested by the software/app that you’re entering it in.
