Pre-requisites: IPv6, Differences between IPv4 and IPv6

An interconnected system of equipment, such as computers, servers, and routers, that can communicate with one another and share resources is known as a computer network. Computer networks are used to make it easier for devices to communicate with one another and exchange data, as well as to give users access to shared resources like printers, files, and software.

Computer networks can be classified as either Local Area Networks (LANs), Wide Area Networks (WANs), or Metropolitan Area Networks (MANs). Whereas WANs cover a wider geographic region, such as a city, country, or even the entire planet, LANs are networks that are limited to a smaller area, such as a house, workplace, or campus.

To allow devices to connect with one another, computer networks use a range of communication protocols and technologies, including Ethernet, TCP/IP, and Wi-Fi. They also organize the actual connections between devices using a variety of topologies, including bus, star, and mesh.

Applications for computer networks include file sharing, online gaming, video conferencing, and remote access. Additionally, they are employed in business and industry to assist vital programs like customer relationship management, enterprise resource planning, and supply chain management.

In conclusion, computer networks are crucial for simplifying data interchange and communication between devices as well as for granting access to shared resources. They have a wide range of uses and are essential for businesses and organizations to operate successfully in the current digital era.

Advantages of IPv6

The most recent version of the Internet Protocol, IPv6, has a number of benefits over IPv4. These benefits consist of:

  1. Larger Address Space: IPv6 offers a substantially bigger address space than IPv4, which is required to support the expanding number of internet-connected devices and users. IPv6 may supply roughly 3.41038 unique addresses, compared to the 4.3 billion unique addresses provided by IPv4, because it employs 128-bit addresses rather than the 32-bit addresses used by IPv4.
  2. Improved Security: IPv6 comes with built-in security features including IPsec, which offers data integrity, authentication, and encryption for internet traffic. As a result, internet communication is more secure and is guarded against harmful assaults like eavesdropping, manipulation, and impersonation.
  3. Simplified Header Format: Compared to IPv4, IPv6 features a simpler and more effective header structure, which lowers processing costs and boosts the speed of the internet connection. The allocation and management of addresses is also made simpler for internet service providers.
  4. Prioritize: IPv6 offers stronger support for QoS features, allowing internet service providers to priorities traffic and guarantee that essential applications, like voice and video, receive the required bandwidth and low latency.
  5. Improved Support for Mobile Devices: In the modern digital world, where smartphones and tablets are becoming more and more common, IPv6 offers better support for mobile devices. These devices can connect to the internet and communicate with other devices more quickly and safely thanks to IPv6.

In conclusion, IPv6 outperforms IPv4 in a number of areas, including address space, security, header format, QoS support, and mobile device compatibility. IPv6 will become more crucial as the number of internet-connected devices and users rises in order to maintain the safety and accessibility of the internet for all users.
