What is an IP address?
The IP address stands for Internet Protocol address. Every device connected to the web has this specific numerical name.
In a few words, an IP address is similar to your home address, but it serves to locate and identify all particular devices you use.

Public vs. Private IP address
What’s the difference between public and private IP addresses?
Despite many similarities, the IP addresses are not the same and have some differences in how they work.
Local IP addresses, also known as private IP addresses, are used in the local address space, behind a router or server.
The private IP address allows the router to determine your device and where to send back the data.
The private IP address allows the router to determine your device and where to send back the data.
How does private IP address work?
A public IP address lets you communicate online and this is what a website sees when you connect to it. Public IP addresses are also used in free Wi-Fi hotspots.
Since the public IP address is exposed, it is vulnerable to privacy breaches, cyber-attacks, and even identity thefts. That's why its protection is a serious matter.

How does public IP address work?
There are two types of IP addresses, IP Version 4 (IPv4) and IP Version 6 (IPv6).

The difference between IPv4 and IPv6
IPv4 is the first design of internet protocol that was created in 1982. Although it is still in use today but isn't widespread because it only supports 4 billion addresses and uses 32 bits.
The more recent IPv6 protocol can support up to 340 billion IP addresses. It is more than sufficient to meet the increasing demand for new IP addresses on the internet.
Since it is incompatible with websites that use IPv4 and vice versa, IPv6 is not as commonly used as it could be.
