SixXS Forum: What can be done better? Sometimes we (SixXS Staff) hear via via that something is not being handled correctly or that certain things are too difficult. Even though we have been busy making information clearer, it seems that still a lot of problems and concerns do not get fed back to us, while we would be the only ones who can actually resolve that problem. SixXS is a free service, but if it isn't any good or of use, then there is no real reason to provide it. Note that logically, if we don't know about a problem or something that might be done different or better, or something that might be really useful to have, then we can't add it either. Thus if you encounter something which is not clear, too difficult, requires explanation or could be done better or in a different way which would improve the experience for all users. As such, if there is anything, do not hesitate to bring it up: * mail it to, or * post it in the forum Thus spread the word and please provide feedback. en-us Copyright 2000-2017 SixXS Mon, 05 Jun 2017 18:00:00 +0000 SixXS Website ( SixXS Forum (SixXS) (SixXS) 30 please make reporting problems less painful <div class="quote">If there is a problem, then usually this means a lot of stress.</div> Why so much stress?

There is no simple answer. It simply does not exist as networks are big and many variable parts are involved. It is almost easier to debug a human body.

Noting also that Tunnel Brokers is just one type of deployment. Not very possible and it would not cover anything remotely near a complete picture. There is not even a single person in the world who would know the solution to all problems, let alone a way to diagnose all problems. Instead, describe your problem in the forums, and then get it discussed and solved. The forums are there for a reason: to help people who have problems and want to see them resolved. Together one can figure it out. There are many many other problems that are way more difficult (eg PMTU issues etc). AICCU has a 'test' mode build in, but it simply traceroutes and pings some things. Note that there is a very nice <a href="">IPv6 Test</a> website. It only tells you that something is broken though, not what is broken.

You are specifying features of an Internet connection that you should be asking for from your ISP, the one you are paying for connectvity. You can get those features, but you will have to pay for them. SixXS is about IPv6 Deployment. IPv6 Tunnelling is a IPv6 Transition technique. At one point there will not be such a free service anymore. Hence, call your ISP, as the freebies will stop at one point: the IPv6 transition will be over. Fri, 27 May 2016 05:51:36 +0000 (Jeroen Massar) Just to say Thank you for a great service! I also want to thank you so much because of the stable service for many years - you guys are really doing a good job. your ipv6-service does ease so many things in the 'modern world' and i also think that you provide a service which shouldnt be stopped. by using sixxs i get a stable fixed subnet which many isps are not able to deliver. also the dns-delegation works like a charm and i've never seen any comparable service by any vps/root-provider. Thank you and keep up the good work! Thu, 26 May 2016 21:47:31 +0000 (Frederik Heissner) Finally got native! I'd like to thank the SixXS team and the ISP's that offer this great service for their efforts over the past few years. I had some issues in the beginning (with my ISP blocking the tunnel and all) but now, finally, after years of promising, our ISP has finally implemented a native IPv6 connection into our home. Unfortunately, even after closing my home tunnel, I still have another tunnel remaining for experiments at university. They won't turn on the IPv6 services on their network for a while, despite surfnet offering them a full native connection, as well as having their website run natively. I'll keep on whining for a native IPv6 service for now, and hopefully they'll roll it out before I graduate. I've also used the experimental tunnel for showing the teachers that all of the network assignments can be done using IPv6. The only things that I had to fall back to IPv4 for were the NAT practicum, as well as showing a wireshark dump of an IPv4 packet, though in the latter case, I also did an IPv6 packet and gave explanations for each and every field there. So, thank you for enabling me to get some bonus points there, as well as just offering simple and usable service.

Most PoPs are restricted to &quot;users in our country&quot;, so is plwaw01 which only caters to Polish endpoints. Only the ruled01 PoP accepts Russian and Ukrainian endpoints. </div> Fri, 28 Aug 2015 11:07:11 +0000 (Jeroen Massar) Closest POP selection for Ukraine Hello, Currently when creating a tunnel from Ukraine SixXS offer to use only Russian POP ruled01, which have RTT near 80ms while for example Polish POP plwaw01 have 15ms RTT. Please enable to choose Polish POPs for users from Ukraine. Thanks. Fri, 28 Aug 2015 10:44:24 +0000 (Mike Tkachuk) possible smaller subnet A /48 subnet is a privilege for folks who want to do more. One has to earn that privilege. If one is unable to earn that, then there is likely something afoul with how one manages the tunnel and thus is not worthy of a subnet. Mon, 29 Jun 2015 19:27:58 +0000 (Jeroen Massar) possible smaller subnet I today thought about the same, but would rather do it differently: Provide a /56 or (maybe) a /60 by default to all new tunnels, somehow included in the price. I would never need a /48 subnet, but at least doing some subnetting stuff would be nice. The problem is rather that one needs to apply for a subnet, costing credits. Currently most Internet providers give out (as far as I know) a /56 or (in my case) a /59 subnet, which is usually completely sufficent for private end users. When giving out a /56 by default and a /48 by application, it should not be difficult for most people.

We are not going to spam people per email as then all email would be ignored. We only send email when something major is happening (eg down tunnel) or somebody requests a new tunnel/subnet etc. Hence all user-actionable items. Also note that there is nothing you as an enduser can do about this. What we can do is typically already limited. <div class="quote">Things I would like to know:</div> See our <a href="">FAQ</a> Thu, 07 May 2015 09:22:04 +0000 (Jeroen Massar) More Info Re PoP Outages Information regarding PoP outages, at least in my limited experience seems to be very minimal. Specifically my PoP is currently offline and no information other than this seems to be provided. More information and possibly email notifications to advise us of the status of our PoP's would be great (the latter I realise would be much more painful to implement) so if we notice odd behaviour on our network we immediately know why (I'm not always home, this would be useful, for example if my partner is and I'm not and she complains that the network is experiencing issues). Things I would like to know: - Estimate on how long this will be down for (even 'unknown' would be better than nothing) - Cause of the issue - If there is anything I should/could be doing as an end-user Thu, 07 May 2015 09:02:38 +0000 (Todd Murphy) More stats and info <div class="quote">Tunnel statistics could be changed not to crop input side of graph in cases where</div><div class="quote">input/output are close to each other.

Remind yourself that a tunnel spans over the IPv4 network. Hence a lot of hops are involved that could do a lot of things to the tunneled packets. You won't be able to make any conclusions from RRDs that get compressed/bucketed over time.

Fri, 27 Mar 2015 06:19:38 +0000 (Tuomas Heino) possible smaller subnet One size fits all. Hence one gets a default /64 and if requested a /48. The SixXS PoPs have thousands of /48s, and if we run out of a /40 we just ask for a new one from the PoP. Hence, no need to start splitting up /48s into smaller prefixes. It is already complicated enough for most people. Wed, 04 Feb 2015 02:01:06 +0000 (Jeroen Massar) Just to say Thank you for a great service! yes, thank you for the service. ooooh, native IPv6, that would be nice. My ISP has vowed to not look at IPv6 for a few years. I could move on, but the only other offering in my area is 256k speeds. Looks like I might be stuck on a tunnel for a while. Wed, 04 Feb 2015 01:45:06 +0000 (Jason lewis) possible smaller subnet Here is an interesting thought. As a home user, I have no need for more than two to four subnets at most (between testing and my divided home and guest networks). I picked up a /48 from but that kinda seems wasteful when the tunnel server might be running out of space. Maybe once a tunnel gets down to the last few subnets, it can be offered as a /56 or something possibly smaller for specified home users. A /56 would allow 65,535 subnets out of the /40 instead of only the normal 256. As it stands, I do not need more than the /64 at this time, so I am not requesting it, but it might be a possibility for home users that might only need a smaller pie. I cannot imagine how a home user would need more than 8 subnets at home. They would have a different tunnel at work. Maybe two subnet definitions say enterprise (/48) and home (/56). Wed, 04 Feb 2015 01:38:44 +0000 (Jason lewis) BGP Support <div class="quote">What is the reason SixXS doesn't support BGP and ASes to announce their own prefixes ?</div> Because the ISPs who provide the PoPs do not provide that service. Also, because peering over tunnels is a bad idea, especially as it is 2014 already. The 6bone experiment was concluded in 2006. Check our <a href="">FAQ: Where can I get native IPv6 transit?</a> where to get native IPv6 connectivity. Thu, 18 Sep 2014 05:25:57 +0000 (Jeroen Massar) BGP Support Hello, What is the reason SixXS doesn't support BGP and ASes to announce their own prefixes ? For South America where there is a single POP this would make a significant difference specially for ISPs. Some of them may have two transit providers but only one provides Native IPv6. An alternative would be to set a tunnel to SixXS announcing its own prefixes being able to keep connectivity in the case of loss of connection to the native transit provider. The only alternative to that now is using which does supports BGP but the nearest POP is Miami and imposes a significant latency. Thanks FF Thu, 18 Sep 2014 02:54:23 +0000 (Fernando Frediani) IPv6 check over SSL requests mixed content The IPv6-Check at doesn't work on current versions of firefox unles you specifically allow mixed content. Some of the scripts to test the connectivity are fetched over http altough the page is accessed via https. Could you eventually look into the possibility to have it all served over https?

The only thing you can do is request a new tunnel from another PoP. If you require credits for that, contact Wed, 04 Jun 2014 17:55:54 +0000 (Jeroen Massar) My assigned POP is "disabled" When my tunnel went down I checked on the web site. It was marked as POP is down. I didn't do anything at that time since I expected it would come back. When it didn't come back I checked again and my tunnel is deleted and the POP is marked as &quot;disabled&quot;. What happened? How do I get mu tunnel back. usphx01 - Highwinds Network Group Inc68.0.133.2102001:1938:81:46::2 PoP is disabled Mon, 02 Jun 2014 19:11:43 +0000 (Michael Reilly) info on nlams01 shutdown Well, I must have missed that somehow. Anyway, thanks for the great service. Mon, 02 Jun 2014 17:49:32 +0000 (Thijs Kroesbergen) info on nlams01 shutdown Emails where sent and there was also an announcement on the news page: <a href="">2014-04-15 - SixXS says a goodbye to Concepts ICT: nlams01 shutting down</a> which was also thus announced through our RSS feed. Hence, you had quite a long time of warning, if you where unaware, check your spam filters. Mon, 02 Jun 2014 15:42:58 +0000 (Jeroen Massar) info on nlams01 shutdown I couldn't find any notification (in my mailbox) about the nlams01 pop being shut down. Did you send out such notification? To me this is kind of a (unpleasant at this moment) surprise.
