Both IPv6 vs IPv4 have several limitations and advantages in various aspects that make each of them a better choice to support the growth of the internet and future technologies.
In today’s digital era, a robust IT infrastructure is required to support global internet connectivity. In the implementation process, we will certainly experience the evolution of internet protocols. We know that the limitations of IPv4 addresses have driven the technological shift to IPv6 as a revolutionary solution. With these limitations, we must seek solutions to capacity issues. The emergence of the Internet Protocol known as IPv6 (Internet Protocol version 6) is a solution that can provide a larger number of addresses and brings significant changes in the design and function of the previous protocol. The comparison of IPv4 vs IPv6 illustrates how this evolution is crucial to meet the ever-growing connectivity needs.
Limitations of IPv6 vs IPv4
IPv4 addresses have a 32-bit format that provides only about 4.3 billion unique IP addresses. The rapid growth of mobile devices and IoT can lead to IPv4 address exhaustion. As digital content continues to grow rapidly and there is a surge in internet traffic every day, these limitations are becoming increasingly apparent. IPv6 technology successfully addresses the limitations of IPv4 addresses. IPv6 features a 128-bit format and an almost unlimited number of addresses, reaching approximately 3.4 x 10^38 unique addresses. IPv6 can provide an unlimited number of addresses to solve the IP address exhaustion problem. IPv6 addresses are displayed as a sequence of hexadecimal digits separated by colons (:).
In computer networks, we often hear the term NAT (Network Address Translation). NAT is a solution to address limitations; however, in practice, NAT is merely a temporary solution that can sometimes create difficulties in network management and connectivity limitations. IPv6 is designed to address some of the issues that NAT might solve in the context of IPv4.

IPv6 vs IPv4
IPv6 is a technology introduced as a solution to the IP address limitation problem in IPv4. IPv6 stands for Internet Protocol Version 6, which is a more advanced protocol with more features compared to IPv4. IPv6 addresses are considered capable of meeting the challenges posed by the increasing number of devices connected to the internet, as the growth of networks is currently very rapid. The differences between IPv4 and IPv6 can be evaluated based on several indicators, including reliability, ease of use, and service security. Here are some differences between IPv6 vsIPv4:
IPv6 is supported by a vast number of addresses to provide unique IP addresses for every device connected to the internet. Additionally, another reason to switch to IPv6 is the insufficient number of IPv4 addresses to support the rapid growth of the internet and the advent of 5G and IoT. With such a large address space, IPv6 can offer a sufficient number of IP addresses, so if the future internet requires more than 100 trillion devices, it would only consume about 5% of the available IPv6 address space.
- Address One of the differences between IPv4 and IPv6 is that IPv6 addresses use a length of 128 bits, which is deemed suitable to meet the larger address needs in the digital era.
- Ease of Address Management IPv6 can address NAT-related issues concerning network management difficulties and connectivity problems. In the implementation of IPv6, NAT is not widely required.
- Security and Quality of Service (QoS) Another difference between IPv4 and IPv6 is that IPv6 provides improvements in several security aspects and supports better quality of service features, helping to meet the increasingly complex network needs.
- Support for New Technologies IPv6 is designed to cope with future technological developments, such as the Internet of Things (IoT) and the global internet growth with more IP addresses. It is known that IPv6 simplifies the router’s tasks compared to IPv4.
- Increased Efficiency The IPv6 header is simpler, making bandwidth usage more efficient and reducing network overhead.
- Additional Features IPv6 includes several additional features, such as autoconfiguration (automatic address setup) and pligrame (address management for accessing services on local networks), which facilitate network configuration and management. IPv6 is also more compatible with cellular networks compared to IPv4.
- Security IPv6 has security features like IPSec, which allows users to encrypt and secure data transmitted over the network.

Implementation of IPv6 in Daily Life
An example of IPv6 usage is in computer network environments, where IPv6 can be used to connect various devices such as computers, printers, and servers. With IPv6, users can also access the internet more quickly and securely, as well as expand their network reach.
Conclusion
The evolution from IPv4 to IPv6 is a significant step in meeting the ever-growing connectivity needs in today’s digital era. The limitations of IPv4 addresses, which provide only about 4.3 billion unique addresses, pose a major challenge alongside the rapid growth of devices connected to the internet. IPv6, with its 128-bit format, offers a solution with an almost unlimited number of addresses, reaching approximately 3.4 x 10^38 unique addresses. Furthermore, IPv6 also provides ease of address management, enhanced security, and better efficiency compared to IPv4. With support for new technologies such as the Internet of Things (IoT) and global network growth, IPv6 is a more advanced protocol ready to face future challenges.
