A Performance Comparison of IPv4 & IPv6

How about we start with the meaning of IP Address: it is an exclusive code or name of a gadget that isolates it from other devices and enables it to communicate with different gadgets. The address is as short as a mail address, Social Security number or Identity Card number utilized in different nations for various people. In any case, for two IP address to impart, they should be connected by means of a Transmission Control Protocol (TCP) which builds up an association between the two to keep up a conversation.

What is IPv4? & Why IPv6 Came to Existence?

The Internet Protocol Four aka (IPv4) is the fourth modification of the IP which was made in 1970 utilizing a 32-piece addressing to framework with four pieces of 8-bits isolated by a period / full stop. IPv4 was turned out when nobody foreseen such broad utilization of the web that the limited number of IPv4 addresses - about 4.29 billion IP addresses - would end unexpectedly early. 

The Internet Assigned Numbers Authority (IANA) declared its designation of the last group of IPv4 addresses in February 2011 while supplies kept on diminishing everywhere throughout the world. In spite of the fact that not all were entirely use, they were legitimately claimed by organizations like IBM and thusly not free for utilize except if exchanged by the organizations that possess them. 

But, with its advent across the web during the 1990s, engineers anticipated the issue not enough IP addresses and started planning IPv6 or IPng (Internet Protocol people to come) to guarantee the accessibility of new locations upon the fatigue of IPv4 IP addresses.

IPv6 Addresses

IPv6 represents Internet Protocol modification 6 which is the substitution of IPV4. It is a 128-piece hexadecimal IP address framework spoke to by 8, 16-piece parts isolated by colons. While the 6th change of IP addresses gives comparable administrations, it gives an apparently vast number of IP addresses (since it works on 128 bits) in this way rectifying one of the critical issues with IPv4. 

Since the addresses are boundless, they are long however IPv6 addresses, explicitly those with placeholder zeros, can be abbreviated by stifling the zeros. In this manner, the IP address 2041: 0000:140F: 0000: 0000: 0000: 875B:131B can get 2041: 0000: 140F:875B:131B.

So, What Exactly Is the Difference Between IPv4 and IPv6?

Most of the websites have put an effort to explain differences within these popular IPV4 and IPv6 versions, but as their explanations are full with a great deal of technical terms that a normal person without a technical background or proficiencies won’t be able to comprehend it easily. Thus, here I have simplified and explain the differences between the two of them in a simple way. As well as this article also cover the pros and cons of both these IP addresses along with their relationship with one another. 

1. IPv4 utilizes the 32-bit numeric sequence whereas IPv6 is based on the 128 bit/hexadecimal address.

The 32-bit sort of IPs are stated in decimal and separated by full stops or periods that appears to be like as follows: 11.16.227.240. On contrary to this number sequence, a IPv6 is a bit comprehensive, and because of the huge numbers of IPs, they are portrayed in form of hexadecimal that is parted by colons.

2. IPv4 has finite IP addresses while IPv6 has infinite addresses

The IPv4 addresses later got depleted with the advent and modification of the web the reason was quite simple as it can only accommodate 2*32-bit addresses, adding up to roughly 4.29 billion.

3. Manual configuration vs Auto-configuration of addresses

IPv4 end users devise addresses every single time they tend to log onto network utilizing the DHCP (Dynamic Host Configuration Protocol) while the IPv6 offers supports for a better version of the relevant protocol also known as the DHCPv6 that provisions auto-configuration enabling their users to “plug-and-play.” In simple words, this states that the devices are able to derive their relevant IPs asap.

4. IPv6 has inbuilt security while IPv4 lacked any

The major difference between the two of these internet protocols is that IPV6 has inbuild security specifications which offer security against any kind of cyber-attacks.

5. Broadcast messages are not available in IPv6

As the Broadcast mails are accessible in the IPv4, but this isn’t the case within IPv6 where the multicast IPv6 FF02::1 performs the same operation.

Key Advantages of IPv6

? Amplified security is one of the top most advantage of IPv6 as the end-to-end encryption and authentication of separate information packets are inbuilt within the IPv6, making machines safer against any cyber-attacks.

? However, this facility was accessible on the IPv4, as it was optional, instead of embedded, thus people who do not possess any technical proficiencies might end up not using this specification. 

? Connect-ability and enhanced scalability of (IoT) that firmly is anticipated, rising to 25 B ‘things’ connected to the internet by 2020.

? Unlimited IP addresses shall be needed for this sort of connection. Although, the modified security within the 6 version is also significant for the loT apps such as banking and smart houses. 

? The best thing with the version with the version is that there shall be no collision with the private IP addresses as it was once a case with the IPV4 protocol, the improved multicast routing enables much more efficient routing as well as the proper use of IPV6 comprises the potential to enhance the web network by boosting its scale. 

Disadvantages of IPv6

Doing an entire switch to IPv6 portrays that you will just access the IPv6 upheld site. It is in this manner fitting to utilize IPv6 applications that work on double stack to empower you to get to both IPv4 and IPv6 sites. 

While Microsoft has been on the front line in the reception of IPv6, Windows doesn't completely bolster IPv6 in light of the fact that to it; colons reference drive letters. 

In any case, Microsoft works around this issue by taking into consideration the substitution of colons in the IPv6 addresses with runs.
