When connecting your equipment to the network you will find different network identifiers, among the best known are the IP and Mac addresses. These addresses allow you to configure your equipment to achieve a satisfactory connection on the network. But you know in detail what it is, what it is for and how to know the MAC address of your PC or Cellphone
The IP address is the one that allows information to reach your device in a correct and exact way, this address contains a number that identifies your equipment or device on the network.
It can be public or private, the public one is placed by the internet network operator, this number is fixed; the private address is the one that allows you to connect to your router.
A router is that device that is used to connect to the Internet, this device makes it possible for different computers to connect to because it distributes their connection.
Previously there was a device similar to the router, it was called Interface Message Processor or IMP, it contained ARPANET, at that time the first network that switched packets.
The International Network Working Group created a Gateway in 1972 with the purpose that several networks could be interconnected.
The router’s function is that network packets are sent on the correct route , immediately storing the packets it has received and also at the same time processing the information, this is done using the protocols already included.
You can find several types of router such as: Office or Home Office in English, used by small businesses that allow them to safely access the virtual network, there are also wireless, core, ADSL and distribution. , each of them uses the IP and MAC address.
What is a MAC address?
A MAC address is the addresses that identifies a computer or device as well as the network connection. This address is already marked by the manufacturer on the NIC card. In case you have a MacBook you will surely be interested in how to know and find the MAC address of my MacBook
A printer, tablet, network repeater, Smartphone, Wi-Fi extender, computer, network disk or NAS, router all have MAC addresses.
A MAC address is defined by the IEEE, which in Spanish means Institute of Electrical and Electronic Engineering, who is in charge of supervising and making the standards for the network connection and Wi-Fi.
Each device contains a unique MAC address; its unique hexadecimal identifier, you can see it because it contains six groups of two digits each with the name of octets.
How to change, configure or clone a MAC address with a router?
All routers already have their address destined from the factory, however if you want to change it, configure it or clone it, then I will show you how to do it:
The Ethernet cable of your equipment, connect it in the same port and also in your router in its listed port, connect the Ethernet port to the port.
Open your operating system be it Windows or Linux. In “Search” type the word “cmd”, press “Enter” and enter the commands.
Enter your browser and enter your router’s IP address (in this case, as a router, its address is 192.168.1.1) in the “Address Bar” option and immediately press “Enter.”
Now in “Start section” enter the username and password, if you do not know the name enter “Admin” or “Password” to enter password.
Enter the option “Network Clone MAC” or “Cheat MAC address”, if you cannot find it, go to Tools or Configure Network and click on the right.
In the option “Clone MAC Address” press click so that the Mac address of your computer can be cloned together in your router with its WAN MAC address.
To culminate in “Save” press click to automatically save the configuration, this will cause your router to restart, if not, disconnect it and immediately reconnect it.
