IPv6 protocol in the Kopiyka provider network

Due to the increasing use of the Internet and the constant evolution of data transmission technologies, there is a huge need for effective IP address management. IPv6, or Internet Protocol version 6, represents a new paradigm of network connectivity that addresses the limitations of IPv4 and opens the path to the unlimited growth of connected devices in the future.

With the depletion of IPv4 resources and the rapid development of the Internet, there was a need to change and modernize network protocols. IPv6, as the successor to the previous version, is designed not only to provide an ample supply of IP addresses but also to improve the efficiency, security, and functional capabilities of the network.

Advantages of IPv6:

- Addresses will be sufficient for many decades in the future. This means that it will be possible to completely eliminate the need for NAT, significantly reducing the load on both client and provider equipment.

- Each device connected to the network receives its "public" IP address.

- Thanks to the improved IPv6 packet header, this protocol provides more space for useful information in packets, improving data transmission efficiency.

- IPv6 incorporates Quality of Service (QoS) technology, automatically assigning priorities to specific services.

- The protocol supports peer-to-peer (P2P) networks, where devices can connect directly to each other without complex detours.

- IPv6 is a higher priority than IPv4 in all services.

- IPv6 protocol supports IPSec traffic encryption, which encrypts data at the source and decrypts it at the destination, making the protocol more secure.

- Version 6 IP addresses can be created and configured automatically using the Stateless Address Autoconfiguration (SLAAC) technology.

- IPv6 simplifies packet headers, making their processing simpler and faster.

Frequently Asked Questions

Do I need to pay extra for using IPv6?

- No, there is no additional charge for this.

Everything works fine for me already; is there a reason to switch to IPv6?

- Yes, there is a reason; everything will work even better with IPv6 :)

Is the provider interested in me transitioning to IPv6?

- Yes, we want all our subscribers to use the latest technologies, so as a provider, we are interested in this transition. We provide free assistance from our specialists to configure Wi-Fi routers for our clients if needed.

Which well-known services have already transitioned to IPv6?

- Facebook, Telegram, YouTube, Google, and many others.

I am your client. Can I use the new IPv6 protocol? Do I need to activate anything in my account?

- Yes, we provide IPv6 addresses to practically all our subscribers. There is no need to activate anything additionally.

Do I need to make any settings on my Wi-Fi router to get an IPv6 address?

- Yes, in most cases, IPv6 is disabled by default on the router. You need to go into the settings and enable it. We provide both IPv6 and IPv4 via DHCP (dual stack).

Do all Wi-Fi routers support the IPv6 protocol?

- No, some routers do not support it. Sometimes support appears after updating the firmware to the latest version. There are routers that claim to support IPv6 but do not work correctly with this protocol.

Which Wi-Fi routers definitely support IPv6?

- All modern models of TP-Link, Mikrotik with firmware version 6 and above, as well as many other routers, work well with IPv6.

From you, I receive IPv6 via DHCPv6; how do I "share" IPv6 to my home devices from my router?

- It's best to enable DHCPv6+SLAAC mode on the router, as some devices work better when their address is assigned via DHCPv6 (e.g., Windows), while others work better with SLAAC (e.g., Android).

How many IPv6 addresses do you provide to me?

- We provide each subscriber with one IPv6 WAN address for the router (/128 mask) and route an IPv6 Prefix Delegation (IPv6 PD) block with a /56 mask. This means that each subscriber receives 2^72 IPv6 addresses, which is 4722366482869645213696 addresses.

Do you provide a dynamic IPv6 address block or a static one?

- Static; this provides additional advantages and the ability to assign a static IP to specific devices from your router when needed.

I configured my Wi-Fi router; how can I make sure that IPv6 is working for me?

- To check, you can visit the website https://test-ipv6.com; the result should be no lower than 9 out of 10.

I configured my Wi-Fi router, but IPv6 is not working for me; what should I do?

- After configuring the router, you need to restart it. If IPv6 still doesn't work, contact us, and we'll try to help with the configuration. If it still doesn't work and your router supports this protocol, we'll send a specialist to you to configure everything on-site.

I have ordered a static IPv4 address service, and it is manually configured. How do I set up IPv6?

- You need to contact our technical support; we will issue a static IPv4 address via DHCP, and after that, IPv6 will automatically work for you.

What is your IPv6 address block?

- Our block is 2a07:f3c0::/29. So, if your address starts with 2a07, it means you received it from us. If your IPv6 address starts with FE80, these are link-local addresses automatically assigned if the device does not receive an external IPv6 address.

Can I get an IPv6 address without IPv4?

- No, we provide both IPv4 and IPv6 addresses simultaneously (dual stack). This is because not everyone in the world has transitioned to IPv6 yet, and if you don't have an IPv4 address, a large part of the internet will not work for you. Our system is configured to automatically issue IPv6 only after your router successfully obtains an IPv4 address.

Do all providers offer IPv6 to their subscribers?

- No, currently only a small number of providers offer IPv6. However, if you are our subscriber, you will receive IPv6.

How to find out which static IPv6 block has been assigned to me?

- You can check the settings of your router or log in to your personal account and navigate to the "IPv6 Protocol" section for this information.
