IPv6 Support for Linux

linux-howto

http://www.linuxquestions.org – Hi folks, As we all know that most of the ISPs are switching from IPv4 to IPv6 due to several reasons. I have some idea about the IPv6 address format, addressing types and knowledge about Linux. So, I want to configure a system so that it can communicate using IPv6 protocol. Some of the services which I want to use on that system are ping( to itself), ssh(to it self). I have little knowledge about networking. So, I would like to open this thread on behalf of all those guys who want to have a knowledge about IPv6 protocol. So, gurus it's your turn to guide us about (HowTos)

Stories similar to IPv6 Support for Linux

I was looking for configuring Slackware to use ipv6 but all instruction I found speak about using an ipv6 tunnel that encapsulate ipv6 request into ipv4 packet and send them to an external router that extracts ipv6 request and sends a reply (or, at least, this is what I understood).

Is that necessary? Isn't there a way to configure a pure ipv6 system?

hi guys, I have a problem about ipv6 on F17. My network support ipv6. I add Code: NETWORKING_IPV6=yes to /etc/sysconfig/network. I use Network-Manager to access network.

After I connect the system to network, I can go to ipv6 sites and use transmission to download via ipv6.

I am trying to implement dual stack for IPv6 support in a IPv4 system. I have configured a DHCP server which gives IPv4 and IPv6 address to the device.

My PC and the VM running on it gets both, IPv6 and IPv4 addresses. The embedded system I am working on needs the dhcpcd command to get IP address.

This is a proposed Canonical Question about IPv6 Subnetting.

I know a lot about IPv4 Subnetting, and as I prepare to (deploy|work on) an IPv6 network I need to know how much of this knowledge is transferable and what I still need to learn. IPv6 seems at first glance to be much more complex than IPv4.

IPv4 blocks IPv6 dns lookups 40 weeks 13 hours ago

I'm using a IPv4 + IPv6 on a server (#1).

Sometimes the IPv4 address is mapped to another server (#2), so #1 isn't accessible via IPv4, but remains accessible via IPv6.

In this case IPv6 dns lookups won't work.

$ ping6 mirror.ipv6.hetzner.de unknown host

If I disable the IPv4 address everything works fine.

$ ping6 mirror.ipv6.hetzner.de PING mirror.ipv6.hetzner.de(2a01:4f8:0:a101::1:1) 56 da

I have setup an Nginx server in a machine which have both ipv4 and ipv6 addresses. Currently, its connected to CloudFlare and only use ipv4. I have 1 ipv4 address assigned to the web server.

Now what I want is, to become fully ipv6. Then connect to CloudFlare. So, if an ipv4 user comes to the site, CloudFlare will make sure that he can visit my ipv6 only site!

Two days agoIndia, along with the rest of the world, saw the launch of IPv6 -- the new internet protocol which aims at replacing current IPv4 in its way. According to the Department of Telecom, 27 Indian websites have already stepped on to the IPv6 platform. Indian ISPs and government agencies have also hinted at following suite soon.

I wonder if I can communicate via IPv6. I know this depends on the ISP. Is there any simple way how to deterimne if my ISP provides IPv6 connection or at least if my router provides this functionality?

If there is not such possibility to use "real" IPv6, what is the best way to simulate it on Ubuntu?
