What is IPv6? Advantages of IPv6 over IPv4


In the globe of networking, IP addresses are like postal addresses for devices connected to the internet. They enable devices to communicate with each other over the internet, allowing us to access websites, send emails, and stream videos. However, the current system of IP addressing, known as IPv4, has limitations that are becoming increasingly apparent as the number of devices connected to the internet continues to rise. To address these limitations, a new version of the IP addressing system, known as IPv6, has been developed.

In this blog, you will gain insights into what is IPv6 and what advantages it has over IPv4. We have further highlighted the technical differences between the two versions, which also convey the improvements that IPv6 brings to the table. You will also learn how the Serverwala Cloud Data Centers can be the best go-to choice for adopting IPv6. 

It does not matter whether you are a network administrator, a developer, or simply interested in understanding how the Internet works. Here you will apprehend the comprehensive meaning and advantages of IPv6. So, let’s get started! 

What is IPv6?

What is IPv6?

IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol (IP). It is devised to substitute the older IPv4 protocol. IPv6 was developed to address the limited number of IP addresses available in IPv4. This limited number was becoming a problem due to the explosive growth of the Internet.

IPv6 utilizes a 128-bit address format, which provides a virtually unlimited number of unique IP addresses. This implies that every device on the Internet can have its own unique IP address, making it easier to connect as well as communicate with each other.

IPv6 also incorporates various other features that make it more efficient & secure than IPv4. These features include built-in support for multicast transmissions, automatic configuration of network addresses, and improved support for mobility and security.

Overall, IPv6 is an important upgrade to the Internet infrastructure that helps to assure that the Internet can continue to grow and evolve in the years to come.

What is my IPv6 Address?

Your IPv6 address serves as a unique identifier allocated to your device by your Internet Service Provider (ISP). ISP enables the IPv6 address to communicate with other devices on the Internet with the usage of the IPv6 protocol.

IPv6 addresses are 128-bit numbers. They are written in hexadecimal notation and separated by colons, for example: “2001:0db8:85a3:0000:0000:8a2e:0370:7334”. This is a much larger address space than the 32-bit IPv4 addresses, which are typically written as four sets of decimal numbers separated by dots (for instance, “”).

Your device’s IPv6 address is employed to recognize it on the Internet and enables other devices to communicate with it directly. This implies that when you browse the web, send an email, or make use of any other Internet-based service, your device’s IPv6 address is utilized to route the data between your device & the destination server.

What is the difference between IPv4 and IPv6? 

What is the difference between IPv4 and IPv6? 

IPv4 and IPv6 are both versions of the Internet Protocol (IP). They are employed to recognize devices and route data packets across the Internet. The major difference between IPv4 and IPv6 is the size of the address space they employ. IPv4 uses a 32-bit address format, which limits the number of unique IP addresses that can be assigned to devices on the Internet. IPv6, on the other side, makes use of a 128-bit address format, which supplies an almost unlimited number of unique IP addresses.

Another difference between IPv4 and IPv6 is the way they handle network traffic. IPv6 contains built-in support for features like multicast transmissions and Quality of Service (QoS) that are not available in IPv4. IPv6 also retains enhanced security features, like built-in support for IPsec encryption and authentication, which help to assure security against attacks and ensure data privacy.

In general, the transition from IPv4 to IPv6 is a critical step in the evolution of the Internet. This is because it permits the continued growth of the network as well as the development of new technologies & services. However, because not all devices and networks support IPv6 yet, the transition is taking time. Also, this needs mindful planning and implementation to ensure a smooth and seamless transition.

What are the advantages of IPv6?

Here are some excellent advantages of IPv6 –

  1. Larger address space: IPv6 provides an almost unlimited number of unique IP addresses. This is highly crucial for the continued growth and development of the Internet.
  2. Improved efficiency: IPv6 makes use of multicast, which further involves an all-IPv6 device well-known multicast address, and a solicited-node multicast address. It allows a single packet to be sent to multiple destinations at the same time, improving network efficiency.
  3. Simplified address assignment: IPv6 includes automatic address configuration. This simplifies the process of assigning unique IP addresses to devices on a network.
  4. Improved security: IPv6 provides IPsec encryption and authentication. This helps to protect against attacks and ensure data privacy.
  5. Better mobility support: IPv6 mobility allows a mobile node to move from one link to another link without modifying the IP address of the mobile node. This helps the process of connecting to the Internet and moving between different networks.
  6. Simplified network management: IPv6 includes features such as neighbor discovery and router advertisement. They streamline the process of managing and configuring networks.

How does IPv6 work?

IPv6 works by providing a unique IP address to each device on a network. It facilitates them to communicate with each other over the Internet utilizing the IPv6 protocol. When a device on a network sends data, it encapsulates the data in an IPv6 packet that includes the source and destination IPv6 addresses, as well as other information such as the packet length, type, and version. The packet is then routed through the network to its destination based on the destination IPv6 address.

Summing Up

IPv6 is known as the latest version of the Internet Protocol (IP) and has several advantages over IPv4. The most significant benefit of IPv6 is the expanded address space. This allows for a virtually unlimited number of unique IP addresses, making it easier to connect and communicate with each other. In addition to this, IPv6 includes built-in support for multicast transmissions, automatic configuration of network addresses, and enhanced support for mobility and security.

As the Internet continues to grow and evolve, the transition to IPv6 is becoming increasingly important to ensure that there are enough unique IP addresses available for all devices & services.
