What is IPv4 and IPv6? What Are The Differences? – Switching from IPv4 to IPv6 is not easy. Many people are not familiar with IPv4, IPv6 concepts, and the possible impact of switching to IPv6. The Internet world is approaching the end of IP addresses. The last block of IPv4 addresses is now separated.
What is IPv4?
IPv4 stands for Internet Protocol Version 4. IPv4 is the most basic technology that allows devices to connect to the internet. When a device is connected to the internet (PC, Mac, mobile phone or other devices, no matter), it is assigned a unique IP address such as 126.96.36.199.
In order to transfer data between devices over the Internet, the two devices must be transferred over the network with their IP addresses. Communication and data transfer between computers without IP addresses is not possible. So, IP addresses are of vital importance to the Internet infrastructure.
