1. IPv4

IPv4 came into existence in the ’70s and can still be seen in most devices. Even though it was the first wave, many devices are connected to the internet using IPv4 addresses.

It consists of 4 numbers ranging between 0-255 and are separated from each other using periods/dots.

However, due to the internet’s ever-evolving nature, all possible variations of this format have been assigned already. To resolve this predicament, a new system to assign IP addresses became essential, and here comes IPv6 in 2012.

2. IPv6:

Organizations like the Internet Society launched IPv6 format on June 6, 2012. It comprises an eight group of four hexadecimal digits. It includes alphabets and numbers, which are separated by colons.

Due to the combination of alphanumeric systems, the number will not be exhausted anywhere soon, and hence a large number of devices can connect through IPv6 addresses.

  • Example of IPv6 address: 2001:0bd8:85a3:0000:0000:9d6b:0370:7334
