IPv6 day 6 June 2012: time to do it again

May 18th, 2012 by

This time for realLike last year, openSUSE will participate again on the coordinated launch of the next-generation Internet protocol IPv6 on June 6, 2012.

Joining the Internet Society and several major Internet companies like Google, Yahoo and Facebook, openSUSE shows again its readiness for the industry-standard technologies including the new standard protocol for the Internet, Internet Protocol version 6 (also known as IPv6).

As we started already last year and did not disable the services since then, this time is an easy win for us: all our services, including wiki, news,  documentation, forums and of course OBS are already reachable via IPv6 and IPv4. Several thousand users have been using our services via IPv6 every day since then.  This year, the openSUSE-Education project also joins us and provides their major services also via IPv6.

So no time to hide any more: try it out and become part of the next generation Internet Protocol users around the world! Your preferred Operating System already supports IPv6 since years now – and a lot of websites and other participants, too.

Both comments and pings are currently closed.

    It will only be “real” when some of the systems will ONLY be reachable using IPv6 and not “also”. ;-)

  2. ICANN gave out the last IPv4 address to continental registries in around 2011-11-xx. ARIN still has 1.12e8 addresses but these will be exhausted. China now has some ISPs that are IPv6 only. We’ll see this in North America and the European Union in a very few years. Goodbye, IPv4.

    The problem is that OBS is still forcedly using IPv4 (like, when workers connect to repserver/srcservers, IIRC) in way too many places.

    I have been using IPv6 on my local network for about 2 years now. If it can be reached by IPv6, either on my local network or the Internet, that’s how I connect. I use a 6in4 tunnel to get IPv6 connection to the Internet. My own personal subnet has about a trillion times more addresses than the entire IPv4 address space. I built my firewall with openSUSE on an old computer and the 6in4 tunnel terminates on it. However, I’d like to see more IPv6 support within the openSUSE distro. For example, the firewall configuration does not appear to support IPv6, though it is possible to configure it in IPTables. It’d also be nice if the DHCP server configuration also supported DHCPv6. There is also a bug, at least in 11.3, where if the Ethernet NIC is configured for IPv4 DHCP, IPv6 support is disabled. This means that even if an ISP offered IPv6, any openSUSE computer directly connected to the ISP would not be able to use it. That said, I’m ready for IPv6 Launch Day and have been for the past 2 years.

    On my NICs I have a fixed IPv4 addresses and apparently the DHCP server in my Internet router gives me IPv6 addresses. Running 11.2 and 11.4 The tests on the Internet give me a full 100% readiness.

      You don’t need DHCP to get an IPv6 address, though it is one of four methods. With IPv6, you can have a MAC based address, a random number based address and manually configured, as well as DHCP. The MAC based address has been the default for quite some time. However, since some people consider that a privacy risk, recent Linux versions, along with Windows, now also create a random number based address. You’d use the random number address when surfing the web etc., but if you have a server, you’d have the DNS point to the MAC based address. The random number address will change periodically and if you run ifconfig, you’ll likely see a few of them, with one current and the others deprecated. There is also the link local address, which is always MAC based and starts with FE80. With IPv6, multiple IP addresses are normal.

      My ISP provides IPv4 addresses via DHCP. I don’t know if they even offer static addresses to consumers. So, until that bug gets fixed, I won’t be able to use their IPv6, when they get around to providing it.

    I may be a bit lost how it works, but I do not have any problems using IPv4 and IPv6 together on my openSUSE systems. Ik tried to post this above because it could help you to further identify the bug you are talking about and which I do not seem to have any problems with.

      The problem is when a NIC is configured for DHCP, IPv6 is disabled. There’s not even an link local address for it. I am currently using IPv6 via 6in4 tunnel, but if my ISP were to offer IPv6, I couldn’t use it on the NIC I use to connect to them. This is on openSUSE 11.3, which I use for my firewall. I am not the only one that has experienced this and there is a bugzilla report on this. I am planning on updating my firewall to 11.4 shortly, so I’ll have to see how it goes with it. Someone else noted that IPv6 is initially enabled, but then turned off during NIC configuration when DHCP is enabled. I have no idea who’s bright idea it was, but using DHCP for IPv4 should never, ever affect IPv6.

    As said I above, I am not an exprt, but it seems to me that it has something to to with your tunneling (I am not tunneling).

    You could either strat a thread about this at forums.opensuse.org or, if you feel confodennt enough you have a case, report it at http://en.opensuse.org/Submitting_Bug_Reports.

      The IPv6 address I’m referring to is the link local, which every interface should have. It has nothing to do with the tunnel, which continues to work well. As I mentioned someone else had determined that it’s actually being turned off by the dhcp client. It should never be doing that.
