What is IPv6? It can be termed as the new generation Internet Protocol version 6, a successor to IPv4. Over the years, the internet has played a major role in sharing information between various entities across the globe which led to a major boom in various fields. Many start-ups came along and many businesses have earned millions. This boom has inspired all most all modern as well as traditional organizations, small or big, to go online and make their presence felt on a global scale. As a result, IP addresses started reaching their saturation point even faster. In order to meet the demand with supply in future, an advanced Internet Protocol version will be required. This requirement led to the innovation of new Internet Protocol technology, IPv6, which is capable of generating trillions of IP addresses.
What is IPv6 address space?
Now many people will have doubts in their mind like, “What is IPv6 internet address generation capacity compared to IPv4?” IPv4 is 32 bits in length and could accommodate only as many as 4.29 billion IP addresses, which at the point of time (1990’s) was considered to be more than sufficient. However, taking into consideration the rate at which the internet connectivity is growing today, the number of IP addresses available are soon going to deplete. Hence, IPv6 was introduced. It is 128 bits long and can accommodate trillions and trillions of IP addresses which would not get saturated for centuries to come, if not infinity.
Apart from providing a vast space for IP addresses, IPv6 has a simplified header with no unnecessary information attached to it. This wasn’t the case with IPv4. Also, IPv6’s header is only twice as big as IPv4’s in spite of being 128 bit long. However, the IP addresses of IPv6 can be much lengthier compared to that of IPv4’s and is as big as 4 times to that of a normal IP address.
How does an IPv6 IP address look like?
What is IPv6 IP address and how does it look like? This is a question that many people may have in their minds. IPv6 IP address, similar to that of IPv4’s, is also used to locate and identify a particular device. However, its structure is a bit different. For example, if you have seen 4 sets of binary digits separated by a dot, it could probably be the IP address of some device.
A typical example of an IPv4 address would be: 255.255.255.0 which has four sets of binary digits. A typical example of IP address for IPv6 would be: 2002:0cd7:65b4:0000:0000:8b3e:0480:2134. which consists of eight groups, and each group has four hexadecimal digits in it. Here each group is separated by colons (:) and not dot. Though the length is a bit long, it has many advantages as well as functionalities incorporated into it. For example, a person using a mobile phone can stay connected to the same IP address even when he is on the move (roaming). This is not possible with IPv4.
What is the future of IPv6?
IPv6 can be simply defined as the future of the internet. The internet version 2 which is soon going to replace the existing internet will be much more secure and faster. When IPv4 was initially launched, developed countries like US, Canada, Australia and many other countries in Europe have taken the major chunk of the IP space keeping in mind their future requirements. However, the internet has bombarded in an unexpected way reaching every nook and corner of the world. Countries like India and China which are fast developing technically, have already started taking concrete steps to replace their entire space with IPv6. IPv6 is designed to provide superior quality internet services, which it will, in the years to come. It is the future of the internet!
