We can explain what IP address, which is the abbreviation of the term Internet Protocol Address, is with a simple example. Just like every citizen has a nationality number, every device that connects to the internet has a unique number. This number is called an IP address. IP address identifies who you are on the Internet. Just as a policeman looks at your identification number to identify you, a website or an app looks at the IP address to which your device is connected, that is, to identify who it is.
Not only the devices we use, but also the websites have a unique IP address. Sometimes they have an IP address shared and sometimes just their own. Usually, websites get the IP addresses of the servers they are located on. Since servers are a device that connects to the internet, they need to go online by obtaining an identification number, just like the devices in our home and in our hands.

One of the things that should not be forgotten is that we cannot connect to the internet without having an IP address. If your device does not have an IP address, then it will not be allowed to access the Internet. The modems we use in our homes today connect us to the internet. If we cannot connect to the internet, it is probably because our modem cannot obtain an IP address. In such a case, we call our internet provider and they intervene in our modem and give a new IP address or investigate the reason for not being able to get an IP and enable it to get an IP. Therefore, the most basic concept that shows whether we are connected to the internet is our IP address.
How about the IP address?
IP addresses consist of four separate numbers separated by dots. In other words, they consist of four 8-bit numbers separated by dots. Address 220.127.116.11 or 18.104.22.168 is an IP address. 192.168.1.1 Is an IP address. The numbers you see like this on your computer make up IP addresses. However, these can also be local IP addresses. For example, your internet provider will give you an IP address such as 84.24.XX.XX when your home internet connection is established. And every device that connects to your modem goes to the internet with this IP address. However, your modem or router also needs to know who the devices connected to it are. If four people at home are connected to the modem, it gives each of them separate local IP addresses. These local IP addresses are usually addresses starting with 198.168.xx. If someone asks you what your IP address is when you go on the internet, it is your internet IP address you should give them, not your local IP address. Often users confuse the local IP with the IP address from which they go to the Internet. This is how you can recognize them.

However, numbers in an IP address can have a maximum of three digits and cannot be greater than 254.
How can I find my internet IP address?
So, since our local IP address is only related to the modem or router, how can we find it when we need the IP address that we go to the internet? There are many ways to achieve this. The easiest way is by entering the Google search engine, “What is my IP Address? Making a search like”. The first 3 resulting websites will tell you you’re IP address.
Alternatively, if you can connect to your modem interface, the internet connection section of the modem interface will tell you which IP address you are connected to. It will show you “Not Connected” even if you have not been able to connect to the internet. In this case, you can call your internet provider and tell them that you cannot get an IP.
What are the Types of IP Addresses?
We can define IP addresses statically and dynamically in two different ways. The so-called static IP is used to describe a fixed and immutable IP number. For example, if you want the service you receive from your internet provider to be with Static IP, they will define you a fixed IP address. And whenever you go on the internet, your IP address stays the same. This IP address stays with you permanently, and nobody else can have this IP address.

Dynamic IP is the type of IP that can change. If you have not requested a static IP, you will be given a dynamic IP for internet services that you connect to at home. In this case, you will be given a new IP address every time you turn your modem off and on.
If you have a website, the IP you have will be static. In other words, this IP address does not change every time your site is entered. Of course, with Cloud systems, it is now possible to assign a different IP to each country. However, the server IP address will basically remain the same.
There are also two types of IP protocols. These are IPv4 and IPv6 protocols. Currently widely used IP addresses work over IPv4. Because it is compatible with all devices. However, these addresses, which consist of four digits and can reach a maximum of 254, are limited. Mathematically, they can be generated up to 4.3 billion IP addresses. In the internet age, this is not enough. With the increase of devices entering the Internet, it will be possible to have an IP finding problem day by day. Therefore, IPv6 protocol is waiting for us for the future.
IPv6 IP addresses are made up of numbers separated by octal blocks and separated by colons. They are written in four hexadecimal digits in each block. For example, 2500: DD93: 1292: 0000: 0000: 0000: 0002. Here, groups containing 0 are ignored to save space and thus do not take up space. All newly released devices now come with IPv6 support and internet standards will change and replace IPv4 in the near future.
