What is IPv6?

Introduction to IPv6, IPv6 vs IPv4, and when to enable IPv6.

IPv6 (Internet Protocol version 6) is one of the latest versions of the Internet Protocol (IP), designed to replace IPv4. It provides a larger address space (128-bit addresses, as opposed to the smaller 32-bit addresses in IPv4), improves security and configuration features, and supports a greater number of devices and more efficient routing. The deployment of IPv6 helps address the issue of IPv4 address exhaustion and supports the growth and development of the future Internet.

IPv6 Address

An IPv6 address consists of 8 groups of 4 hexadecimal digits (each group is called a block) separated by colons, for example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 addresses can also use a double colon (::) to represent a series of consecutive zeros, for example: 2001:0db8::7334.

IPv6 vs IPv4 (Differences between IPv6 and IPv4)

  1. Larger address space: IPv6 provides a vastly expanded address space compared to IPv4, allowing for more efficient addressing of devices and networks.
  2. Improved security: IPv6 includes built-in security features, such as IPsec, which enhances data integrity, confidentiality, and authenticity.
  3. Enhanced auto-configuration: IPv6 enables easier and more efficient network configuration through stateless address auto-configuration, simplifying the deployment and management of devices.
  4. Better support for mobile devices: IPv6 offers improved support for mobile networks and devices, allowing for seamless connectivity and mobility.
  5. Improved multicast performance: IPv6 includes native support for multicast communication, enabling more efficient distribution of data to multiple recipients.
  6. Reduced broadcast traffic: IPv6 reduces the reliance on broadcast traffic, leading to more efficient network operation.

Should I Enable or Disable IPv6 Protocol?

Enable IPv6

  1. Faster Downloads: Having a public IP allows for faster P2P downloads, enabling quicker discovery of other nodes, accessing more download data, achieving faster download speeds, and reducing the likelihood of interruptions in downloads.
  2. Interconnectivity: Due to the scarcity of IPv4 addresses, home networks are typically assigned private or dynamic public IP addresses, making it impossible to access their own websites directly via domain names from the outside. Communication between networks relies on public IP addresses, and the unlimited addresses of IPv6 will provide a better interconnectivity experience.
  3. Enhanced Security: IPv6 is built on a foundation of security, authenticating at the network layer, encrypting data, and verifying IP packets, ensuring end-to-end data security for users and preventing data hijacking.
  4. Future Development: As more services and infrastructure transition to IPv6, the future of networking will increasingly rely on this technology.

Disable IPv6

  1. Personal Network Environment: If the current network environment does not support IPv6 or if most services are not optimized for IPv6, enabling IPv6 may result in slow webpage loading or the inability to open applications properly.
  2. Limited Device Support: Although IPv4 and IPv6 coexist, not all devices and networks support IPv6. Additionally, some regional ISPs do not allocate IPv6 addresses to individual users.
  3. No Need for IPv6: If you already have a public IPv4 address that meets remote access or other requirements, or if you only use the network for watching online videos, daily chatting, or playing online games, IPv4 is sufficient for your needs.


EdgeOne also supports the IPv6 protocol. With the proliferation of internet-enabled devices, the older IPv4 addresses are being exhausted, making IPv6 support imperative. By supporting the IPv6 protocol, EdgeOne ensures that its architecture is future-ready.
