My IP is localized, various information, such as the hostname, IP address, service provider, and DNS are displayed. But what do they mean? You will find some answers to these questions in the text below.
The number in the largest blue block at the top of the page, labeled "my IP", corresponds to your public IP. In most cases, this public IP is your router's internet address. This is the number you give when asked for your IP address.
This IP address should not be confused with your "local" IP address. Indeed, if you are behind a router (which is probably the case), it also assigns an IP to identify your computer or terminal (mobile phone, tablet, etc.) via its integrated DHCP server. This IP is your address on your LAN (Local Area Network). You can obtain your local IP address by going to the "my local IP" section.
IP means Internet Protocol, so this identification number is assigned to a terminal on an IT network using the internet protocol. This IP enables the device to identify itself and communicate with other terminals connected under the same protocol.
There are 2 types of IP addresses: 32-bit encrypted version 4 and 128-bit encrypted version 6. IPV4 are currently reaching their limits in terms of availability. In theory, there are 2 32, or 4,294,967,296 V4 IP addresses available. There are not as many in practice, as some are reserved. Although this figure may seem relatively large, there are hardly any more V4 IP addresses available today. IP V6 is, therefore, gradually starting to replace this protocol, making the number of potential addresses almost inexhaustible.
A service provider is the company that manages your internet connection, giving you access to the worldwide web. Several technologies are available, so you may have an ADSL, coaxial cable, or fiber-optic connection.
Your DNS, automatically provided by your service provider, is identified by an IP address. This server translates domain names into IP addresses, acting like a sort of switching system. Without this server you would not be able to display any websites in your browser. For example, when you type google.fr in your browser, your computer queries the DNS server, which replies that google.fr is located on the server with the IP address XX.XX.XX.XX. The connection is established and the page you want is displayed in your browser.
The hostname is the full name associated with your IP address on the internet. It is unique and identifies your specific IP address. It consists of a subdomain associated with the domain of your internet service provider.
My ip address change every day that's boring...
