In the realm of computer networking, there are numerous technical terms and concepts that can be confusing, even for the most tech-savvy individuals. Two such terms that are often misunderstood or used interchangeably are WiFi address and MAC address. While they are related, they are not exactly the same thing. In this article, we will delve into the world of networking and explore the differences between WiFi address and MAC address.
Understanding MAC Address
A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) or a network interface card (NIC) for use as a network address in communications within a network segment. It is a 48-bit or 64-bit address that is usually represented as a series of six groups of two hexadecimal digits, separated by colons or hyphens. For example, a MAC address might look like this: 00:11:22:33:44:55.
MAC addresses are used to identify devices on a network and are typically assigned by the manufacturer of the network interface card. They are used in the data link layer of the OSI model to identify the source and destination of data packets.
How MAC Addresses Work
When a device sends data over a network, it includes its MAC address in the data packet. The receiving device then uses this MAC address to determine where to send the data packet. MAC addresses are used in both wired and wireless networks, and they play a crucial role in ensuring that data packets are delivered to the correct device.
Understanding WiFi Address
A WiFi address, also known as an IP address, is a unique address assigned to a device on a network that uses the Internet Protocol (IP) to communicate. It is a 32-bit or 128-bit address that is usually represented in dotted decimal notation, with four numbers separated by dots. For example, a WiFi address might look like this: 192.168.1.100.
WiFi addresses are used to identify devices on a network and are typically assigned by a router or a DHCP server. They are used in the network layer of the OSI model to identify the source and destination of data packets.

Key Differences Between WiFi Address and MAC Address
While both WiFi address and MAC address are used to identify devices on a network, there are some key differences between them.
- Length: A MAC address is 48-bit or 64-bit, while a WiFi address is 32-bit or 128-bit.
- Format: A MAC address is represented as a series of six groups of two hexadecimal digits, separated by colons or hyphens, while a WiFi address is represented in dotted decimal notation, with four numbers separated by dots.
- Assignment: A MAC address is assigned by the manufacturer of the network interface card, while a WiFi address is assigned by a router or a DHCP server.
- Layer: A MAC address is used in the data link layer of the OSI model, while a WiFi address is used in the network layer.
Why WiFi Address and MAC Address are Not the Same
WiFi address and MAC address are not the same because they serve different purposes. A MAC address is used to identify a device on a network at the data link layer, while a WiFi address is used to identify a device on a network at the network layer.
In addition, a MAC address is typically assigned by the manufacturer of the network interface card, while a WiFi address is assigned by a router or a DHCP server. This means that a device can have multiple WiFi addresses, but only one MAC address.
Relationship Between WiFi Address and MAC Address
While WiFi address and MAC address are not the same, they are related. In fact, a WiFi address is often associated with a MAC address.
When a device sends data over a network, it includes both its WiFi address and its MAC address in the data packet. The receiving device then uses the WiFi address to determine where to send the data packet, and the MAC address to determine which device on the network to send it to.
How to Find WiFi Address and MAC Address
Finding your WiFi address and MAC address is relatively easy. Here are the steps:
- WiFi Address: To find your WiFi address, follow these steps:
- Open a command prompt or terminal window.
- Type the command “ipconfig” (for Windows) or “ifconfig” (for macOS or Linux).

What is a WiFi address?
A WiFi address, also known as a WiFi MAC address, is a unique identifier assigned to a network interface controller (NIC) for use on a network. It is used to identify a device on a network and is typically used in conjunction with the Internet Protocol (IP) address to facilitate communication between devices.
In the context of WiFi, the WiFi address is used to identify a device on a wireless network and is used by the WiFi router to direct traffic to the correct device. WiFi addresses are usually 48 bits long and are expressed in hexadecimal format, with each byte separated by a colon or hyphen.

A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for use on a network. It is used to identify a device on a network and is typically used in conjunction with the Internet Protocol (IP) address to facilitate communication between devices.
MAC addresses are usually 48 bits long and are expressed in hexadecimal format, with each byte separated by a colon or hyphen. They are used in the data link layer of the OSI model to identify devices on a network and are used by network devices such as routers and switches to direct traffic to the correct device.
Is WiFi address the same as MAC address?
Yes, a WiFi address is the same as a MAC address. Both terms refer to the unique identifier assigned to a network interface controller (NIC) for use on a network. The terms are often used interchangeably, although some people may use “WiFi address” specifically to refer to the MAC address of a wireless network interface.
In practice, the terms “WiFi address” and “MAC address” are often used to refer to the same thing, and the distinction between the two is not always observed. However, technically speaking, a MAC address is a more general term that can refer to the address of any network interface, while a WiFi address specifically refers to the address of a wireless network interface.
How are WiFi addresses assigned?
WiFi addresses, like MAC addresses, are assigned by the manufacturer of the network interface controller (NIC). The assignment is typically done during the manufacturing process, and the address is stored in the NIC’s read-only memory (ROM).
The assignment of WiFi addresses is governed by the Institute of Electrical and Electronics Engineers (IEEE), which is responsible for maintaining the global database of MAC addresses. The IEEE assigns blocks of MAC addresses to manufacturers, who then assign unique addresses to each NIC they produce.
Can WiFi addresses be changed?
Yes, WiFi addresses can be changed, although it is not a common practice. Some network interface controllers (NICs) allow the user to change the MAC address, although this is not always possible.
Changing a WiFi address can be useful in certain situations, such as when a device is being used on a network that requires a specific MAC address. However, changing a WiFi address can also cause problems, such as disrupting network connectivity or causing conflicts with other devices on the network.
Why are WiFi addresses important?
WiFi addresses are important because they provide a way to uniquely identify devices on a network. This is necessary for network devices such as routers and switches to direct traffic to the correct device.
WiFi addresses are also used for security purposes, such as to authenticate devices on a network or to filter out unwanted traffic. In addition, WiFi addresses can be used to track the location of devices on a network, which can be useful for network management and troubleshooting purposes.
How can I find my WiFi address?
You can find your WiFi address by checking the settings of your network interface controller (NIC) or by using a command-line tool. The exact steps will depend on the operating system you are using and the type of NIC you have.
On most devices, you can find the WiFi address by going to the network settings and looking for the “MAC address” or “WiFi address” field. You can also use a command-line tool such as “ipconfig” (on Windows) or “ifconfig” (on macOS or Linux) to display the WiFi address.
