What is an IP address?
The IP (or Internet Protocol) address is a unique identifier that all electronic devices connected to the Internet have. It is generally available in two flavors IPv4 and IPv6. In this excerpt, we explain what it is and how to better exploit it in your web projects or on a daily basis.
The IP address in the world of the web
In the world of IT development, IP is unavoidable. Indeed, each domain name is associated with an address (of the server) to point to the net. When you want to create a website and point it to the internet, you have to buy a domain name. Then, you must point this domain name to a web server (physical or virtual machine). Usually, for testing purposes, a developer can only use an IP address to display the website. The IP address in the case of a website allows you to locate the position of your web server and can be a means of discovering the origin of a certain activity. For example, several cybercrime organizations validate the origin of a domain name in order to better predict counterattack strategies.
When you buy a domain name, you must associate it with a physical or virtual machine to connect it to the web. This machine is connected to an IP address that the world can use to track where your web server came from.
An IP address for a consumer
When you purchase the internet connection, your provider associates your connection with an IP address. The latter is the one you can detect with our tool. You can, however, hide this information with what is commonly called a VPN.
Why a VPN?
A VPN is a device you can set up to change your IP address. This will return a bad value when someone wants to find out your location. As an advantage, this will allow you to hide your activities on the web more effectively. This is especially useful if you want more control over your privacy. This approach is often used by cyber criminals to do dangerous online activities. Hence the need to be wary as well.
