The IP address is the identifier your computer has when it connects to the Internet or your local network. If necessary, it may be useful to know it. A few clicks are enough to make it appear on the screen.
Each device that connects to the Internet (computer, PC, tablet, etc.) is identified by a series of numbers separated by periods. This license plate on networks is called IP address, for Internet Protocol. Except that unlike the license plate of a car, it can change (it is not mandatory) at each connection. With myip you can know a lot.
Note that this is the private or local IP address (type 192.168.0.10) assigned to the computer or device as part of the home network. And not the public IP address (type 220.127.116.11), the one that is assigned by the network through which you connect your ADSL connection, a Wi-Fi connection, etc.
You may need to know your IP address, for example, to set up a particular Internet connection or software, to allow others to connect to your computer, or to troubleshoot network problems. Here’s how to proceed:
With Windows 10
In the notification area of the taskbar, at the bottom right of the screen, click the icon for your Internet connection. In the list that appears, click your active connection, the one under which the term Connected appears.
In the window that appears on the screen, click again on the icon of the connection where it is marked Connected. Various parameters are displayed, including your IP address in front of the IPv4 Address line.
How can I find my IP address, and what is it for?
An IP address is an identification number assigned to a computer connected to an Internet network . In concrete terms, this number serves to identify the machines and to enable them to interact with each other by exchanging data on the Internet . Each computer is assigned a fixed IP address (if it is still lit) or a dynamic IP address (if the computer is frequently restarted). This registration is conducted by ICANN (Internet Corporation for Assigned Names and Numbers), which manages IP addresses globally. Currently, the most used standard is the Ipv4 protocol, consisting of a series of 4 numbers, but following the increase in the number of computers connected, this protocol will be gradually replaced by Ipv6, which offers more possibilities. The IP addresses can be used to block or allow access to a computer to certain resources, or to know the user profile (e.g., geolocation based on IP is used by Google ). The implementation is done completely automatically, without the user has any particular setting to achieve on his machine.
Know your IP address from your computer
By default, operating systems have several internal tools for knowing the IP address of the computer. On Windows, open the command prompt and type the ipconfig command. It is also possible to go through the Network and Sharing Center and view details of the Local Area Connection. In Mac OS, open the Network panel in System Preferences and display the active connection. The IP address is in the form of a series of numbers separated by dots, for example, 192.168.1.30.
