There are not as many in practice, as some are reserved. In theory, there are 2 32, or 4,294,967,296 V4 IP addresses available. IPV4 are currently reaching their limits in terms of availability.
There are 2 types of IP addresses: 32-bit encrypted version 4 and 128-bit encrypted version 6. This IP enables the device to identify itself and communicate with other terminals connected under the same protocol. IP means Internet Protocol, so this identification number is assigned to a terminal on an IT network using the internet protocol. You can obtain your local IP address by going to the "my local IP" section. This IP is your address on your LAN (Local Area Network). 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 address should not be confused with your "local" IP address.
This is the number you give when asked for your IP address. In most cases, this public IP is your router's internet address. The number in the largest blue block at the top of the page, labeled " my IP", corresponds to your public IP. But what do they mean? You will find some answers to these questions in the text below. My IP is localized, various information, such as the hostname, IP address, service provider, and DNS are displayed.
