* Do you know what IPv4 and IPv6 are?


Suggested article: IPv4 vs IPv6 and where did IPv5 go?

An Internet Protocol address is also known as IP address. It is a numerical label which is assigned to each device connected to a computer network which uses the IP for communication. Every time you see some network settings, there are IPv4 or IPv6. Let’s explain them!

  • IPv4 - It was the first version of IP. It was deployed for production in the ARPANET in 1983. Today it is the most widely used IP version. It is used to identify devices on a network using an addressing system.
  • IPv6 - It is the most recent version of the Internet Protocol. In contrast to the IPv4 which uses 32-bit addresses, the newer version uses 128bit addressing. To see the difference we will start with one example of IPv6: “2001:0db8:0000:0042:0000:8a2e:0370:7334”. It has 8 groups, double the number of the previous. Each group has 4 hexadecimal (hex) digits and the groups are separated by colons.
