IPv5 Your professional partner in IPv4-to-IPv6 transitions

Professional IPv6 consultancy for efficient migration

IPv5 - the organization

We are IPv5, an international consulting organisation with our main location in Eindhoven, The Netherlands.
Since 2005 we are promoting IPv6, raising awareness about the changes required.
As of 2008, in addition to raising awareness we are offering IPv6 consulting services to organisations worldwide.
Our team of experienced internet veterans (which can still explain IPv6 in human terminology) and IT specialists (ranging from embedded software network stack developers with IPv6 knowledge up to high-level-programming-language experts) are working hard to help get your organisation running dual-stack and give training your IT staff on IPv6.

Why do we need IPv6?
The Internet has experienced a phenomenal increase of devices accessing the Internet.
Because of this increase, IPv4 addresses are running out.
The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security.

Who we are

We are IPv5, providing worldwide IPv6 Consultancy services on IPv4-to-IPv6 transitions from our main office in Eindhoven, The Netherlands.
We have been promoting IPv6 since our start in 2005, raising awareness about the changes required to hard- & software to get IPv6 implemented correctly. Since 2008, in addition to raising IPv6 awareness, we are offering IPv6 consulting services to organisations worldwide, helping to get IT infrastructures ready for this next step in connectivity.

Our team of experienced internet veterans (which can still explain IPv6 in human terminology) and IT specialists (ranging from embedded software network stack developers with IPv6 knowledge up to high-level-programming-language experts) can get your organisation running dual-stack and give training your IT staff on this subject.

IPv4

IPv4 is the current version of the internet protocol, which has been in use since 1982.
ipv4 in the final stages of exhausting its unallocated address space.
(what you are probably using now)

As the IoT (Internet of Things) is progressing, we will call each device communicating over the internet a device, instead of naming computers, laptops, tablets, televisions, routers, gateways, pvr individually.

IPv6

Internet Protocol Version 6 (IPv6) is the next generation of the Internet Protocol.

With IPv6, every computer has an worldwide-unique address on which it can communicate directly with any other device in the world.
This is one of the big advantages of IPv6 that makes techniques like NAT (name-address-translations from private to public ip addresses) obsolete. However, without proper protection in place (like firewalls), the internal IT infrastructure could be made much more vulnerable from internet attacks.

Some of the major advantages of IPv6 are:
- Larger IP address space: IPv6 has 128-bit address space or 4 times more address bits compared to IPv4's 32-bit address space. This large address space will provide enough address space for many decades to come. In real terms, every residential or commercial customer will be able to receive more address space from TWC than the entire IPv4 address space contains – several billion IP addresses!
- Better security: IPv6 includes security in the underlying protocol. For example, encryption of packets (ESP: Encapsulated Security Payload) and authentication of the sender of packets (AH: Authentication Header).
- Consideration to real time: To implement better support for real-time traffic (such as videoconference), IPv6 includes a flow label mechanism so routers can more easily recognize where to send information.
- Plug and play: IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically.
- Better optimization: IPv6 takes the best of what made IPv4 successful and gets rid of minor flaws and unused features

Where is the IPv5 protocol?

Although IPv4 and IPv6 exist, there was no IPv5 protocol, and if you came here expecting information about a IPv5 protocol, there is none. The name of the new, future-proof internet protocol jumped from IPv4 to IPv6, skipping IPv5.
IPv4 existed long before the start of the internet, and describes how computers on networks (like the internet, but smaller) can communicate with eachother.
When IPv4 was developed, no one imagined a world like the one we have today, with half the planet using cellphones and connected devices can be seen everywhere. The amount of available addresses was limited (saving precious bytes), and it was more than enough for the first decades. When the internet was growing at an exponential rate, it was quickly running out of IPv4 addresses. Tricks like NAT were used to circumvent some of the limitations, but introduced others, where devices could not access other devices using NAT.

IPv6, the successor to IPv4 has only gained traction the last few years. One of the main reasons to solve the problem with the limited number of addresses, but many other issues of the IPv4 protocol have been resolved and new features have been added that can greatly improve media streaming (IP television) and other things that were unimaginable in the 20th century.

There is a lot of misunderstanding about IPv6. We at IPv5 will help you understand IPv6, and implement it correctly.

Here at IPv5, we help organisations upgrade their IT infrastructure from IPv4 to IPv6.

Why should everybody use IPv6 now?

1. IPv4 devices can only contact other IPv4 computers on the internet.
2. IPv6 devices can only contact other IPv6 computers on the internet.

This means IPv4 devices cannot communicate with IPv6 devices, and vice versa. This adds another layer of complexity: if a website would switch over to use IPv6 and would stop using its IPv4 address, any IPv4 device would be unable to visit that website anymore.

IPv6 requires proper preparation, implementation, testing, testing and more testing. We cannot switch from one day all-IPv4 to the next day all-IPv6: the internet would probably break, not to mention the fact that with timezones, if it's monday at your location, it could already be tuesday in another place in the world.

/We won't switch from IPv4 to IPv6 all at the same moment, the world is so big and the internet has become such a major part of everbody's life

The solution is using one of the transition modes, which more or less mean that you

Transition methods:

–      Dual-Stack
–      Encapsulation
–      Translation

The best way of transitioning to IPv6 is called 'running dual-stack'. Running dual-stack means that all device(s) have both an IPv4 as well as an IPv6 address and can connect to the internet on both protocols. When you would use the internet, it first tries to setup an IPv6 connnection, and if that is not available, it will fall back to use the IPv4 internet protocol.

Only when all devices in the world are able to send and receive using IPv6, IPv4 will become obsolete.

Our job

We start by looking at your current IT IPv4 infrastructure, and discuss with your IT department about the changes  required to run dual-stack.

Our professionals have years of experience with IPv6, firewalls and IT + networking in general, and can help get you running dual-stack quickly.

How to check which internet protocol you are using right now.
If your internet provider is up-to-date, you should be running dual-stack right now! Check it by visiting http://test-ipv6.com/ it will show you how ready you (and your internet provider) are.
