IPv6 some questions

[Silver-0-surfer]

I just have some questions regarding ipv6.

1) is it possible to get an IPv6 address in south africa and if so, where do you get it from (do you get 1 or an certain block?)

2) Is there routing between ipv4 and ipv6 globally? meaning if I have an ipv6 address can I access anything that only has ipv4?

Thanks

Fixed IPs are quite rare unless you are running a business which really requires a fixed IP. Most businesses will rather use dynamic DNS and dynamic IPs.

Why do you specifically want an IPv6 address? What do you want to do with it? You should be able to get it just like you would a static IPv4 address, but I think your chances are quite slim at finding that in SA at present.

Yes these is routing between IPv4 and IPv6. The IPv6 address is essentially an IPv4 address with a bunch of digits added. So for example all IPv4 address could be 0.0.0.0.0.0.(0....0).IPv4 address.

A few local ISPs have IPv6 capable infrastructure, but I don't know of any that offer IPv6 to customers by default.

Any ISP that operates on ADSL will not be able to provide you with native IPv6, since the Telkom ADSL Infrastructure is incapable of handling IPv6.

You will likely need a Tunnel broker of some sort if you want IPv6. They can assign you a block from their allocations.
www.he.net or www.sixxs.net are the easiest, but they don't have PoP's in South Africa, so your latency on IPv6 will be increased.

And no, there is no way to send traffic to an IPv4 host from IPv6 or from IPv6 to IPv4.

There is a way - read up on 6 to 4 Tunneling and 4 to 6 Tunneling.

We running this in our global network already..

Take a look at http://tunnelbroker.net/

Tunnelling IPv6 traffic over IPv4 networks and IPv4 traffic over IPv6 networks is not the same as an IPv4-only computer talking directly to an IPv6 server.

In order to get from IPv4 to IPv6 you must install/activate the tunnelling services on the client side. These tunnelling mechanisms can also be slow and unreliable. They are a good way to get basic IPv6 access but most operating systems will now prefer IPv4 over tunnelled IPv6 due to the reliability issues.

There IS however - a way to connect from an IPv6 only client towards an IPv4 only server through a gateway. I've been using this for a while and its pretty reliable. In some recent testing there are only a handful of major applications that won't function fine on an IPv6 only Internet connection.

If you had a host that ran IPv6 only on one end of a network cable, and a host that had only IPv4 on the other end, there would be no way to communicate between the two.

The only way (as ambo has already pointed out), is through an intermediary or gateway that is dual-stacked and does the Protocol Translation.

I've been running my home network 100% IPv6 for a few months through a NAT64/DNS64 gateway, and so far no-one in the family even notices.
Skype complains, and I'd imagine that if I had gaming consoles they would complain about online gameplay.
