The Benefits of IPv6


Network setup and configuration Nowadays, it is so complex that IPv6 is designed to support the automatic installation and tuning of systems. configuration) to facilitate allocation, IP address (Address Renumbering), multi-homing, and even network management. Plug-and-play

2. Broadcast / Multicast / Anycast

In IPv4, part of the IP address was allocated as a broadcast address, but in reality broadcast communication was unnecessary and wasted bandwidth.Multicast was more efficient communication and became popular with IPv6. It is designed to support Multicast group address and cut off the broadcast address.

IPv6 also increases Anycast communication capability, allowing more devices to One IP address is allocated to the same number, which means any device can respond to the information sent to that Anycast address.

3. Mobile IP

IPv6 supports the same mobile Internet use as IPv4, but Mobile IPv6 is more efficient than Mobile IPv4 in that it can transmit data through the shortest possible routes, without relying on intermediary devices for forwarding. Optimization) and IPSec can be used to prevent packet theft in the middle of the road.

4. Security

All routers and network devices in an IPv6 network are configured to support IPSec deployments.There are also two types of Security Payloads, Authentication Payload and Encrypted Security Payload, to support stable and secure traffic under the Network Layer. Instead of relying on the Application Layer as in IPv4 networks.

5.Virtual Private Network (VPN)

Traditionally, in IPv4 networks, VPN services were performed by using IPSec to encrypt all network layer data, which would be a problem if the source or destination network had a Network Address Translation (NAT) because the encryption had to end before reaching the destination for. IPv6 networks do not have such a problem. Since NAT is no longer needed, Extended Header, called Authentication Header and Encapsulated Security Payload, can also be used to support secure VPN usage.


IPv6 was designed to support the quality assurance of service from the start. This can be seen from the Flow Label and Traffic Class locations in the header, although in the IPv4 header there is a Type-of-Service location. But not widely used As there are no standard configurations and not all routers can process ToS locations, IPv4 has previously let the layers below handle QoS, for example through MPLS technology.

7. Maximum Transfer Unit (MTU)

The minimum MTU in an IPv4 network is 576 bytes and is added to 1280 bytes in an IPv6 network. The minimum MTU length increase. This will make the data transmission in IPv6 network more efficient. It reduces the proportion of header information to all data.

The Insight

If your organization offers a public website Or the Internet or Mobile Application can provide faster service by using IPv6 compared to IPv4 in this section, benefit from network-address translation (NAT) to connect to the Internet via IPv4 with your service provider.

Providers lacking public IPv4 that allocate a unique address to all service members are routed through NAT, which is via public IPv4. Traffic running over IPv4, if it runs over one or more NAT, is backhauled to a central connection, or large-scale NAT, where clients connect via TCP / UDP, connection and bandwidth limitations are available.

For NATing, the route of TCP and UDP connections is required, which can cause delays in the delivery of packages.

While IPv6 and cloud-access are associated with data security. On the other hand Both mobile and broadband users now have native IPv6 on their mobile devices. IPv6 packages do not go through a network NAT and connect directly to the Internet.The lack of NAT in IPv6 means that TCP and UDP are validated to not coordinate with IPv4.

Although the IPv6 package is larger And it has a wider range of connections (multiple protocols around it), with hardware-accelerated like IPv4, and for systems that support both IPv4 and IPv6, Happy Eyeballs is an algorithm that determines which protocol is the fastest. And choose to use Which enhances the user experience

Facebook, LinkedIn, Google, and others have released statistics showing that IPv6 was faster than they had expected.

The Asia-Pacific Network Information Center (APNIC) is one of the five Regional Internet Registries or Internet Registrations. It monitors the Round-Trip Time connection of IPv4 and IPv6 packages from around the world, indicating that IPv6 has lower latency than IPv4 in all regions except Asia.

Enables end-users to access the Internet via IPv6 to increase the efficiency of the traffic of customers visiting retail websites. This can be done with corporate users. Connect to the Internet from the corporate network.

Most operating systems already support both IPv4 and IPv6, so if an enterprise network uses an enterprise host to connect to IPv6, end users can connect to the Internet via. dual-protocol Automatically Unfortunately, most organizations still use dual-protocol hosts on IPv4 only

If an organization has enabled IPv6 on a wireless network They will benefit from IPv6.

IPv6 deployment should start with all connected devices. Therefore, organizations should verify device compatibility with IPv6 and have Internet security settings that support IPv6, including firewalls, DNS servers, load balancers, Web application firewalls (WAFs), and cloud security agents.

While perimeter on IPv6-enabled is the next step in the development of IPv6 on core networks and pushes it towards end-users.

Another advantage is Get closer to customers

Able to recognize the customer’s true IP address (real IP), when the customer enters the website, it will log with the IP address which can be verified through against threat-intelligence databases and filtering the identity of the connection. Which can be dangerous

Some websites try to use IP addresses as part of their identity, with username and password linked to the IP address for added security. From people trying to log in using an IP address that has been used before

While the benefits of IPv6 are vast, it can help ensure security without IPv6 NAT can detect which devices a customer is using, where some moderators or administrators consider IPv6 to be more vulnerable.

Security for end-users

User’s real IP disclosure May be viewed as unsafe Even knowing that, for security reasons, IETF data NAT is not an essential security for IPv6. And untrusted incoming connections are blocked, so even if the global IPv6 address is known, we cannot access the system.

IPv6 provides some ways to maintain user privacy by masking the Interface Identifier (IID), which is part of the unique identifier. The organization does not want to disclose personal information. This includes the MAC address information in the IID on the user’s device.

The method varies, for example if the network uses a protocol such as stateless address autoconfiguration (SLAAC) or RDNSS that extends privacy or uses Stable SLAAC.

Additionally, when using DHCPv6 to direct IPv6 to the host, the IID values ​​are randomized, so they are safe for the end-user.

What is IPv6 Address?

Internet Protocol Version 6 is the latest network layer protocol. Which is a system that allows communication across the network And even though the concept has been in place since 2008, But it only started to replace IPv4 in 2017.

IPv4 is a 32-bit number with four numbers, each with two or three digits that will identify your device and location.A typical IPv4 address looks like this:

If you want to find out your IPv4 address you can find it here.

It is expected that by the year 2010 All IPv4 addresses will be used.
And to solve that problem, a network layer protocol was created to increase the number of unique addresses. And this is where IPv6 starts.
IPv6 is a 128-bit address with eight numbers, and each string has four digits. And separated by colons (:). A typical address looks like this: 2018: 0ab6: 84a2: 0000: 0000: 7a2b: 0271: 7435.

Type of IPv6 Address
IPv6 addresses are divided into three types.

Unicast – It is one to one communication. It is a transmission of information from a single source to a single destination.
Multicast – It is a communication from one to many destinations. Which is forwarding the information to a destination consisting of multiple devices
Anycast – Same as multicast, but the source selects the closest destination to send the data.

IPv6 Benefits

More addresses
Increase the efficiency of connecting in p2p network.
Higher speed
With automatic configuration
Efficient in routing
It has strong security.
Has a higher conversion rate


IPv4 is also more popular.
IPv6 and IPv4 cannot communicate directly and must have a server.
VPN providers rarely upgrade their servers to support IPv6.
Because IPv6 has many benefits Network engineer, data center, technology company And many mobile network operators take advantage of IPv6. IPv6 is the choice that experts choose and should be the consumer’s choice as well.

Will IPv6 leak your information?
When you use a VPN service, you will be provided with an IPv4 address, which will protect your privacy and keep you anonymous online. If you try to communicate with an IPv6 server, it is likely that your true IP address will be exposed. Make your personal information disclosed as well.

Using the best VPN service to prevent iPv6 leaks will help you stay safe online. Here are three of the best service options.
