You may have come across the recently trending topic of IPv4 IP addresses exhaustion and how IPv6 is replacing IPv4. Below we have broken down all the different aspects related to IPv4 and IPv6 and how they impact the global internet community.

Firstly, let us understand how IP addresses around the world is distributed and who distributes them. There are 5 Regional Internet Registries (RIR) globally who allocate IP addresses.

The 5 RIR’s are listed below:

  1. The Asia-Pacific Network Information Centre (APNIC) serves East Asia, Oceania, South Asia, and Southeast Asia

  2. The Réseaux IP Européens Network Coordination Centre (RIPE NCC) serves Europe, Central Asia, Russia, and West Asia

  3. The American Registry for Internet Numbers (ARIN) serves Antarctica, Canada, parts of the Caribbean, and the United States

  4. The Latin America and Caribbean Network Information Centre (LACNIC) serves most of the Caribbean and all of Latin America

  5. The African Network Information Center (AFRINIC) serves Africa

The RIR’s have a depleting number of IPv4’s (Version 4 of IP addresses) since its designers while creating the IPv4 addresses in the 1980s did not foresee that the 4 billion unique IP addresses may eventually run own and had no idea how large the web would become. To counter the shortage of IP addresses, its successor IPv6 was created.

The most common question asked is What is IPv4 & IPv6? So, let us first give you an introduction to both.

Introduction of IPv4 & IPv6 and how it works:

IPv4: IPv4 is the 4th version of IP addresses with a limit of 4 billion IP addresses. Since IPv4 works on only 32-bit addresses, the address space is limited to 4294967296 (232) addresses.

IPv6: The solution to providing IP addresses for the next and future generations brought in the creation of IPv6, the 6th version of IP addresses works on 128-bit address providing a larger address space, allowing 2128, or approximately 3.4×1038 addresses

How to symbolize IPv4 & IPv6:

IPv4: IPv4 Address representation is expressed in any notation of a 32-bit integer value, often written in the dot-decimal notation, which consists of four groups of eight of the address expressed independently in decimal numbers and parted by dots. The numbers can range from 0 to 255. For example, the IP address represents the 32-bit decimal number and in Binary is 01100111.11101101.01110001.00001101.

IPv6:  IPv6 address representation consists of eight groups, separated by colons, of four hexadecimal digits, in 128-bit notation. The full representation may be simplified by several methods of notation; IPv6 address example2001:0db8:0000:0000:0000:8a2e:0370:7334 becomes 2001:db8::8a2e:370:7334. (Source: Wikipedia)

Difference between IPv6 and IPv4:

Some of the major IPv4 and IPv6 differences are:




Length of address

128-bit address notation

32-bit address notation

No. of addresses

Infinite addresses

approximately 4.3 billion addresses

The appearance of the IP address

hexadecimal numbers separated by colons 

four 1 byte decimal numbers, separated by a dot 

Ping style



Benefits of IPv6:

  • The router’s task is streamlined in IPv6 compared to IPv4.

  • Mobile Network compatibility in IPv6 more than IPv4.

  • IPv6 can bear bigger payloads than IPv4.

  • IPv4 is still used by 99%, IPv6 is new and used by less than 1% of the networks.

  • IPv6 can multicast compared to IPv4.

  • The IPv6 packet header is simpler than IPv4 header.

  • IPSEC is more secure and robust in IPv6 compared to IPv4.

What Will Happen to IPv4? – Depletion:

Presently in the world of internet, IPv4 and IPv6 coexist. The main reason for IPv4 address depletion happened is inadequate capacity in the original Internet infrastructure design; however, there were many pressing reasons which have enhanced the weaknesses.

Some of the reasons for IPv4 exhaustion were:

  1. Increase in mobile users had increased the need for more IPv4 addresses for digital communication, especially the new generation 4G mobile connections require IPv6.

  2. Increase in router and broadband modem connections worldwide

  3. Increased use of the internet all over the world. Currently, China stands first in the largest number of internet users, roughly 829,000,000 and India stands in the second position with 560,000,000 internet users, leaving the US in third place with 292,892,868 internet users (source:, stats till 31st march 2019).

  4. Unsystematic use of Internet users by allocating huge blocks of IP addresses to Universities, large companies, and sub-netting caused inefficient use of IP addresses.

Rise of IPv6:

The transition from IPv4 to IPv6 is crucial for

everyone globally. There are three main areas where IPv6 will be implemented from a technical point of view:

  • Software Applications

  • Major Operating systems

  • Hardware systems

Mobile manufacturing companies and desktop computer manufacturers have already been providing IPv6 support to their desktops, laptops, tablets and mobile phones. IPv6 has gradually been implemented to be used by organizations since 1993; a major event which used IPv6 in 2008 was the Summer Olympic Games in Beijing.

The IPv6 deployment worldwide statistics has placed T-Mobile USA in number one position with 94.11% and Reliance JIO Infocomm Ltd. at number two position with 90.72% according to statistics from 12th June 2019 by

TES Affiliate Conferences Prague 2019:

The immense rise in IPv6 deployment stories by countries and companies have brought IPv6 into the spotlight at European Summit Affiliate Conferences 2019 in Prague to be held from 13th September 2019 – 16th September 2019. Being a major believer of new and advanced technology, Alpha InfoLab, Inc., has been a brand ambassador of sorts in the IT industry in India to promote IPv6 deployment, buy, sell or lease unused IPv4 and assist businesses to transition from IPv4 to IPv6.

Alpha InfoLab, Inc’s. President, Mr. Ajay Goyal will be addressing at the European summit Prague 2019 as one of the esteemed TES speakers to present a seminar on 14th September 2019 at 11.00 a.m. in the ‘Prague C Seminar Room’ on the trending topic, ‘The Importance of working with IPv6 over IPv4 in Digital Marketing’.

Mr. Ajay Goyal will be stressing and elaborating his expert views on the following key points at the conference:

  • What is the meaning of IPv4 and IPv6?

  • How does it affect our working?

  • Why one should go for IPv6, urgently?

  • What are the advantages of working with IPv6?

  • What are the security features of IPv6?

  • How can you get benefited while releasing IPv4?

  • Comparison between IPv4 and IPv6

Alpha InfoLab, Inc. wishes Mr. Ajay Goyal and his team a very successful and productive business meeting at one of the Best Affiliate Conferences to Attend in 2019 at Prague.
