IPV4 vs IPV6 – Important Differences to know!

Filed Under: Random
IPv4 V S Ipv6

Hey, readers! In this article, we will be focusing on the differences between IPV4 vs IPV6. We will be understanding the basic differences between them in terms of networking!

So, let us begin!!

What is IPV4 in networking?

IPV4 stands for Internet Protocol version 4. It has 4 address spaces of 32-bit integer values.

Components of IPV4:

  • Network: Identifies the category of the assigned network.
  • Subnet: Networks that hold a huge amount of hosts are divided into subnets.
  • Host: It identifies the machine on the network.

What is IPV6 in networking?

IPV6 stands for Internet Protocol version 6. It has 8 address spaces of hexadecimal digit values.

It is also known as Internet Protocol next generation in this field.

Difference between IPV4 and IPV6

Let us now have a look at the major differences between IPv4 and IPv6 through the below mentioned table–
