What is an IP Address?

Why are, there these IP addresses that we are likely to hear even in a cafe in daily life? First of all, let’s say you don’t have to know this. If your business or area of ​​interest is not the internet, technology or network, this information is useless in your daily life. At Now You Tech, we will briefly talk about what IP is and what it does.

What is an IP Address?

An IP address is an address used by devices connected to the internet or other packet-switched networks using the TCP / IP protocol to exchange data with each other over the network. To put it more simply, if the internet was a shopping site; Your service provider would be your shipping company, and your IP address would be your home address.

In other words, based on this definition, the ultimate purpose of the IP address is to know the addresses of the devices that, are connected to the internet or that have created its network, so that it can deliver the data to that address and also know where the transmitted data comes from.

How to Create an IP Address?

Today, the most commonly used IP address type is IPv4. I will explain its formation through this version. IP addresses consist of four combinations of values ​​between 0 and 255, which we call bytes. IP addresses must be unique in the open network (for local networks this may differ)

According to this formation, there may be 256 * 256 * 256 * 256 = 4.294.967.296 IP addresses on the world, ie on the Internet. However, as we can all guess, there are many more Internet-connected devices in the world, and as predicted before, the IPv6 version was removed years ago, as this type of IP address will not be sufficient in the future and will cause some problems. So if IPv6 is not widely used now, how can so many devices connect to the internet with a unique identity? The answer to this question is in a subheading.

Local Networks

A local area network is a computer network that connects computers and vehicles in a limited geographical area such as homes, schools, laboratories and business buildings.

If we talk about it, I want to give an example from my own house. 2 computers in my house and 4 phones are connected to the internet! So am I using 6 different unique IP addresses in this case? No. My devices are connected to my modem over wifi. In other words, like the internet itself, my modem has its network, and only people connected to my modem can connect to this network. This network is called a local area network. Our modem assigns an IP address to each of our devices to communicate in the local network.

Since this is a local network, these IP addresses, cannot be accessed from the internet so they are considered unique in themselves. As a result, although I have 6 internet-connected devices in my house, I have one unique IP address, given to my modem by my service provider. Since all 6 devices are connected to this modem, the IP addresses of 6 devices are the same on the internet. The modem’s task is to direct the data coming to these IP addresses to the devices.
