How good work Steam in a IPv6 Only Network?

[perfect aim]

Can i use Steam with a internet conection without IPv4?

[aiusepsi]

I'm pretty sure Steam is IPv4 only.

[perfect aim]

do you know anything about plans to make Steam IPv6 ready?

[Satoru]

Steam is IPV4 only as well as most game's networking stacks

There is no such thing as a 'pure' ipv6 since most of the internet ist still ipv4 you still have to be able to support ipv4 in some way if you connect to the internet.

The most is not all and how long have the most conections still IPv4? I will still gaming games from today in 5-10 Years and tunneling is not Performant.

It exisit no reason to wait with the IPv6 Implementation.

Ask your ISP how much ipv6 they have.

IPv4 exhaustion is a real problem that's happening right now. Several of the regional RIRs have already resorted to rationing plans. In Europe or Asia-Pacific, you can only get about a thousand more IP addresses per organisation, ever.

This is especially going to be a problem in fast-growing places like China; either you move over to IPv6 wholesale, or you get stuck with an awful IPv4 network topology that may involve multiple levels of NAT.

Companies should right now be updating their software to support IPv6. In many cases, it'll be as simple as making the data structure used to store IP addresses longer.

I have allready IPv6 since 1-2 Years, without i ask.

Yes, and Valve are careless if there do not work at IPv6 Implementation.

The Difference Between IPv6 and IPv4 IP Addresses

An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf

As the only difference seems to be the length of the IP address uses with no performance increase or any other reason beyond increasing the number of IP addresses available, there is no hurry for the net to change except to sell more domains that use IP addresses.

Your set-up may be IPv6, but that does not mean your ISP uses it. Mine is also IPv6, but any time I check my IP on a site, it shows as an IPv4 since that is what my ISP assigns me.

How is it careless? Why should they if the only difference is the number of IP addresses available?

It would help if you explained your reasoning behind it instead of just stating your opinion.

There are differences between the IPv6 and IPv4 protocols, but yes, the most pressing reason is that the number of IPv4 addresses is running out.

This means that starting very soon, people who need IP addresses won't be able to get them any more. That'll have really serious consequences for the future of the Internet, especially in the fast-growing and developing parts of the world. If you can't address the hosts, you can't route the traffic, then you don't have a network any more.

As the problem of IPv4 exhaustion rolls on, more and more people will either have only IPv6 connectivity, or horribly broken IPv4 connectivity, behind layers of NATs. That's not a sustainable future for the Internet. This is already starting to become a problem in some parts of the world, as they started out with far fewer IPv4 addresses than we're allocated to North America.

What companies can do is set up their software and services so that it can work with both IPv6 and IPv4. For example you can access Google, Facebook, Bing, Yahoo etc. over IPv6 today, if you have IPv6 connectivity.

See sites like this: http://www.worldipv6launch.org/wp-content/uploads/2013/05/ipv6-launchiversary.png for more information.

People who run services have a responsibility to be ready for this transition, especially if they're planning to serve areas of the world that are already starting to feel the pinch. Asia-Pacific (including China) is a great example of this.

Most games don't work on an IPv6 only LAN, even if you have a NAT64/DNS64 router to the IPv4 internet. The issue is the OS's socket functions do not automatically convert IPv4 addresses to the IPv4-mapped IPv6 address format. The developer has to do it manually to connect to IPv4 servers.
