IP addressing: what is it and how does this technology work?
IP addressing is an essential technology that allows devices to communicate on the internet. It is a hierarchical addressing system that assigns a unique address to each device connected to the network.

These addresses are used to identify individual devices on the internet and to route data between them.
What is IP addressing and what is the structure?
IP addressing is a type of numerical system that allows devices to communicate within a network, just like we use on the internet.
A unique address is provided for each device on the network so that we can identify them and communicate with each other.
IP addressing works by assigning a unique numerical address to each device connected to a network, whether local or global.

The basic structure of IP addressing is made up of four sets of numbers separated by periods. Each set of numbers represents an octet, or 8 bits, of binary information.
O IP adress It is made up of 32 bits in total, divided into four octets, meaning there are a total of around 4.3 billion unique IP addresses available.
How it works?
IP addressing works using a routing system. When a device sends a data packet over the internet, it is divided into small pieces called packets.
Each packet is then addressed with the IP address of the destination device and sent to the nearest router.
The router checks the packet's destination IP address and decides the next best path to send it.
This is done using routing tables that list the IP addresses of networks and devices connected to them. The router forwards the packet to the next router on the route until it reaches its final destination.
Types of IP addressing
When we talk about IP addresses, there are two different types, IPV4 and IPV6. IPV4 is the original IP addressing system, and is still widely used today.
However, with the rapid growth of the internet and the limited number of IPv4 addresses available, IPv6 was created, which uses 128-bit addresses and allows for a much greater number of unique addresses.
IP address security
When a device is connected to the internet or a local network, it is identified by a unique IP address that can be used to track its activity on the network.
It can be an important component in understanding how they can be used for user protection and privacy.
IP addresses can be used to identify the location of the device, websites visited, searches made, and other information that can be used to profile the user.
This information can be used for personalized advertising or even for malicious purposes, such as identity theft or monitoring illegal activities.
At times it may be necessary to know the IP address of your computer, and to find this you will have to enter the search bar on your computer. Windows and type “cmd”, then press enter,
A command prompt screen will open, in it you can type “ipconfig” and press enter, scroll until you find “Ethernet Adapter” or “Wireless Network Adapter”.
In this section you will find the IPv4 address and the number will be next to it.
