IPv4 vs IPv6 – Comparison of the two Internet protocols
Computers and devices can communicate over the Internet using the Internet Protocol (IP).

There are currently two versions of IP: IPv4 and IPv6 . Both are used to label devices connected to a network, but they differ in several ways.

In this article, you will learn the differences colombia phone number data IPv4 and IPv6 and the future of each version of the Internet Protocol.

let's get started.

What is an Internet Protocol?
Internet Protocol (IP) is a set of rules responsible for routing data across networks and delivering it to the correct destination.

When sending data across a network, a computer divides the information into bits called data packets , which makes the data transfer process faster and more efficient.

Each of the data packets contains both the source and destination IP address . An IP address is a unique identifier assigned to all devices connected to the Internet or computer network.

Just as a postal address is needed to send a letter, a device also needs a correct IP address to send information across a network.

Here's an example of what IP addresses might look like:

210.3.252.42

IP addresses are distributed by the Internet Assigned Numbers Authority (IANA), an organization in the United States responsible for managing the pool of IP addresses.

Keep in mind that an IP address is different from a domain , which is a website address that is easier to remember than numeric IP addresses.

What is IPv4?
Internet Protocol version 4 (IPv4) is the first and most well-known version of the Internet Protocol. It relies on the best-effort delivery approach , which does not guarantee data delivery or quality of service.

This means that users may experience delays and other issues depending on the current Internet traffic load.

IPv4 is also a connectionless protocol, which transmits data packets without ensuring that the destination device is ready. The advantage of this type of protocol is that it can send packets through alternative routes in the event of network congestion or router failures.

This version of IP uses a 32-bit address , the format most people are familiar with when talking about an IP address. An IPv4 address consists of four decimal numbers, separated by three periods, ranging from 0 to 255, such as:

192.4.3.144

The 32-bit address space can provide approximately 4.3 billion addresses. However, some large blocks of these addresses are reserved for private networks and are not available for public use.

What is IPv6?
Internet Protocol version 6 (IPv6) is the latest version of IP, also known as Internet Protocol Next Generation (IPng).

It works similarly to Internet Protocol version 4 (IPv4), which provides unique addresses for all devices connected to the Internet. However, unlike IPv4, IPv6 uses a 128-bit address instead of the 32-bit address format.

A 128-bit address space offers approximately 340 undecillion addresses, or 1,028 times more addresses than IPv4.
