An IP address is a unique identifier assigned to each device connected to a network using the Internet Protocol (such as the Internet or a local network). It allows machines to be located and identified for exchanging data.
An IP address is a unique identifier assigned to each device connected to a network using the Internet Protocol (such as the Internet or a local network). It allows you to locate and identify the machines to exchange data.
There are two main types:
- IPv4 : composed of 4 numbers (0 to 255) separated by dots, for example
192.168.1.1. - IPv6 : composed of 8 groups of 4 hexadecimal characters, for example
2001:0db8::1.
Example :
When you access www.example.com, your computer uses the server’s IP address to establish the connection and transfer data.
To remember:
- Identifies a device on a network.
- Essential for data routing on the Internet or a local network.
- Two versions: IPv4 (short, limited) And IPv6 (long, unlimited).
- Maybe static (fixed) or dynamic (assigned automatically by DHCP).
