Difference Between IPv4 and IPv6 Protocols

Before we define the main difference between IPv4 and IPv6, it is very important to know what IP is first. IP which is better known as Internet Protocol is largely defined with Internet Engineering Task Force which is also used in communication between networks. Protocols are always needed to maintain some control, flexibility and consistency when it comes to the transfer of data at a high rate. For networks to communicate amongst one another they require some clear protocols or rules that need to be followed. The transmission of data is also a secondary purpose of internet protocol while IPv4 and IPv6 are two types of protocols which sometimes considered same with almost nothing different. However with the advancement of knowledge and technology at the same time, the research has shown that both protocols are very different from each other. IPv4 is basically to identify hosts while the IPv6 gives you information to overcome the shortage of IP address space.

    IPv4 which is mainly for identifying the different types of hosts, you need to understand that this IP type certainly is very different and the concept of similarity between two protocols is very much misguided. This type of IP works with class-full and class-less concepts of internet technology and has many other aspects to understand well. You also need to understand that IPv4 has different classes from A, B, C, E. You can say if first class which is A has 8bits of 32 bits identifying the network as well, the class B will have different amount of bits in it. As the limitation of the address spaces, CIDR Classless Inter-Domain Routing has also been introduced to help out the difficult process. You can say that if address space increase the information data will also increase in less time. As CIDR also introduce different types of network and their variable lengths.

    IPv6 on the other hand, works and provides help to overcome the shortage of the IP address space. It works with having 128 bit number with address of 2128. This, IPv6 also gives some relief and more flexibility to overcome difficult addressing as we need to focus on the overall network where IPv6 is considered very essential. You should also know that IPv6 basically provide and represented with eight groups of 16 bit hexadecimal. For example 2607:f0d0:1002:0051:0000:0000:0202:0004.

    You can also write the single occurrence of digits as it is shown in the example. 2607:f0d0:1002:0051:0000:0000:0202:0004
