https://www.sixxs.net/forum/?msg=better&from=rss 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 info@sixxs.net, 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 http://cyber.law.harvard.edu/rss/rss.html SixXS Website (https://www.sixxs.net) SixXS Forum info@sixxs.net (SixXS) info@sixxs.net (SixXS) 30 https://www.sixxs.net/forum/?msg=better-15721229-15721245&from=rss https://www.sixxs.net/forum/?msg=better-15721229-15721245&from=rss <div class="quote">If there is a problem, then usually this means a lot of stress.</div> Why so much stress?

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.

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.

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.

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.

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.

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 he.net 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).

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 HE.net which does supports BGP but the nearest POP is Miami and imposes a significant latency.
