What is an IP Address

What is an IP Address ?

For starters, IP is the diminutive of Internet Protocol (IP). There are 2 types of IP addresses: the V4 IP address and the V6 IP address. At present, the most common type of IP address is IP V4. V4 IP addresses are composed of 4 series of numbers from 0 to 255 separated by dots. Example 0.121.210.255 The problem is that the number of IP addresses in the world is limited to 4.3 billion for about 7 billion people on earth. It was therefore necessary to invent a new protocol of IP addresses which you certainly know under the name of: IP V6. The V6 IP address protocol is totally different from the V4 IP address.

An IP address allows more precisely to identify a device connected to the Internet (computer, printer, surveillance camera, …). But an IP address is also associated with every Internet site in the world. It is easier to type in the address bar of your browser www.mywebsite.com rather than 121.10.211.155 You have understood, if you have a website, it necessarily has an IP address assigned. Without an IP address, the Internet would not exist! It is thanks to this famous IP address that the corps locate the wanted individuals.

You will tell me: are we hunted? The answer is yes. But rest assured, the corps ask your ISP your IP address only if it is really necessary. That’s why more and more people are turning to Virtual Private Network (VPN). But what is it ? Until now we used proxy that allowed to change IP address in order to be able to go on the Internet anonymously. But the problem of a simple proxy is that the data or at least the searches you are doing are not encrypted. This is why the VPN has appeared. It has the advantage of changing your IP address but also to encrypt all that you do. Of course, if you have nothing to hide, the VPN will not help you.

There are several types of VPNs to hide your IP address and encrypt your searches. There are free and paid. The advantages of paying VPNs are that you can choose your IP address from several countries in the world and your connection is not slowed down.

As for your IP address, it can be fixed or dynamic. A fixed IP address has advantages. You can install a nas server (hard disk with remote access) to put your data in it. You can have access to all your data from anywhere. Some ISPs provide you with a fixed IP address by default and others a dynamic IP address. To find out, you have to ask them. A dynamic IP address changes with each connection, ie each time you restart your ADSL modem or every 24 hours (in general).
