When you walk down the street, smartphone scan nearby Wifi networks and transmit its MAC address. Device Tracking: Because the MAC ID is a unique number, it can be used for tracking.For example, the airportвЂ™s Wi-Fi network can provide a maximum of 30 minutes of the Internet for free, and then it prohibits a specific MAC address from accessing Wifi. Device identification: Many Wi-Fi networks at the airport and other public Wi-Fi hotspots use the MAC address of the device to identify it.MAC address filtering: networks can use MAC address filters, allowing only devices with specific MAC addresses to connect to the network.When a device is connected, it always receives a specific IP address if it has a corresponding MAC address. Static IP: Routers allow you to assign static IP addresses to computers.In addition to the basic network usage, MAC addresses are often used for the following purposes: As a result, there is access to the Internet only for a device with the registered MAC address. The reason is that the ISP assigned your IP address and registered the MAC address of your network card with you. The simplest example is when you connect your computer to the Internet, then decide to connect to another computer through the router connected to it, but there is no Internet. Based on the Mac address, the Internet service provider can control the access to the internet. The most common use of MAC address is access filtering. For example, you may have two different MAC address for Ethernet and for Wifi. Actually, there are as many addresses as network interfaces are supported by Media Access Control. It is important to understand that there are several MAC addresses possible.

In short, the IP address has a strategic aim, indicating where the packet of information should be transferred globally, while the MAC address has a tactical value and it contains information regarding the nearest device to which the packet has to be transmitted. In fact, they are used simultaneously but have different purposes and meanings. The average user, who is not a computer geek, often confuses the IP and MAC addresses and cannot clearly explain where each of them is used. Here is a MAC address example: 00: 1B: 44: 11: 3A: B7.

The MAC serial number consists of six groups of two characters separated by colons. It is actually used for information exchange between computers on the local network. While the IP address is logical and it can be changed by the network administrator, the MAC address is on the hardware and it is permanent. The MAC address is registered on the network card when it is created in the factory. MAC ID (Media Access Control) is a unique digital number assigned to each computer on the network, more precisely not to a computer, but to a network card.
