IPv6 Day-Learm About IPv6

IPv6 is a new version of IP, which is the main transport protocol & routing of packets used on the Net.

IP is a base layer in Net & you use it every day without realizing it. When you log on the Net, you have an IP address that identifies you uniquely on the Net.

I have no idea much about networking. Concretely, what IPv6 will change for me?

The version of IP currently most often used is version four, more often known as IPv4.

IPv6 will let you benefit from the latest in network: in the event you have IPv6 now, you would have a better guarantee of security on the Net, the tedious configuration would not exist, you can stay connected while moving without causing issue the performance would be as nice or better than you currently have.

In addition, IPv6 will enable the emergence of new applications, currently blocked by sure limitations of IPv4. Since this is a future, it is difficult to foretell exactly which applications will benefit from IPv6 successfully.

You must recognize of work that all this won’t happen overnight lorsqu’IPv6 will be available.

Finally, IPv6 will enable everyone to have an address (& even more!) On the Net, which is far from the case. For example, it is now impossible for all students worldwide are directly connected to the Net with current technologies.


Without applications that leverage has to offer IPv6, then IPv6 is primarily a gizmo that can use the computer. Nevertheless, they can say the same for all technologies: no applications, the expertise is only marginally useful. But with a tiny imagination, can recognize that IPv6 can permit new things.

ome say that IPv6 is clearly a gimmick, but the answer is much more complex than that.

As a simple example. To Free, the Freebox makes use of address translation (NAT) when in router mode to permit different computers behind it to access Net. Although convenient, this greatly complicates things if everyone on of the computers in query require to make VoIP (or provide the same service) simultaneously.

Answers to questions What are the differences of IPv6 over IPv4? IPv6 is it essential? can also see how nouveux IPv6 offers advantages that ought to benefit & how IPv6 can be useful.

To summarize, say that IPv6 is a gadget is technically true, but mostly reveals a lack of anticipation of future needs & future applications. IPv6 is not a gimmick.

IPv6 is necessary?

Yes and no. The dearth of IPv4 addresses has led to the emergence of new techniques now used extensively to connect home networks to the Net. For example, in Free, NAT is used when the Freebox is in router mode.

NAT is effective for applications such as web or e-mail, but is notoriously more complex applications requiring a port opening on the Net. In some cases, it makes it very impossible, as for VoIP applications, including those based on the standard SIP protocol. Applications like Skype manage to operate using non-standard ways and through a variety of relay servers, as well as through mechanisms for detecting NAT, which complicates the method unnecessarily.

Another aspect is that increasingly services (including net sites) located in Asia and Africa are only obtainable by IPv6, and this will only increase. Indeed, the shortage of IPv4 addresses is a reality outside of Europe and The united states. If IPv6 is not obtainable for users in France, then they can not access positive services hosted in Africa or Asia.

IPv6 poses Does not issues of a privacy point of view and / or anonymity?

IPv6 is not, for now, absolutely essential. But some limitations in IPv4, and even techniques to circumvent them, and the shortage of IPv4 addresses increasingly complicated things and show some interest in IPv6.

Plenty of people think at first that as it is feasible to have an IPv6 address for each person on the planet, IPv6 presents a feasible issue because people would facilitate monitoring and intrusion in to private life: it would be a kind identity card which they could get rid and prevent anonymity. It is legitimate to have an interest in this type of issue and they think that IPv6 is in no way an IPv4 largest issue from this point of view.

Indeed, already with IPv4, an IPv4 address is used to connect to the Net. This IPv4 address can be used to locate the that is connected (this is how people were assigned to court for sharing files on peer-to-peer). might think that the NAT is a barrier to this type of identification, but this is not necessarily the case (as a priori, the head of NAT is responsible for traffic passing through it) and anyway, it is also feasible to do NAT with IPv6.

Finally, they note that IPv6 includes support from the design to security, including through providing authentication and encryption of packets.

Furthermore, with IPv6, it will be feasible to make use of, for the same person, different addresses for different purposes (which may not be feasible with IPv4), as plenty of IPv6 addresses obtainable for each connection. This case does not guarantee anonymity, but it can help to blur the tracks.
