Fwd: [OCCAID] 6bone addresses going away in June
Enough talk about viruses and unpatched hosts! <grin> Maybe if we try hard enough, we can create a Y2K syndrome for the removal of 3ffe:: from global routing? ----- Forwarded message from Mike Bran <mbran@occaid.org> ----- Date: Fri, 6 Jan 2006 10:27:11 -0500 From: Mike Bran <mbran@occaid.org> To: occaid@cnacs.occaid.org Subject: [OCCAID] 6bone addresses going away in June Everyone- Pursuant to RFC 3701 calling for "6BONE Phaseout" 3FFE prefixes remain valid only until June 6, 2006. Those who are still using 6BONE based address space and transit service must take appropriate action now instead of waiting to the last minute. We will begin filtering 3ffe::/16 traffic by the earlier of: (i) June 6 2006; (ii) when transiting traffic sourced from or destined to 3ffe address space drops below 5% of our aggregate network traffic. --mikeb Regards, Mike Bran IP Global Network Operations Center OCCAID, Inc. w: http://www.occaid.org p: +1 617 459 4051 x 500 e: mbran@occaid.org _______________________________________________ OCCAID Mailing List November 1, 2005: OCCAID 5th Year Anniversary! http://www.occaid.org Occaid@cnacs.occaid.org is the list posting address. db-admin@cnacs.occaid.org is the human contact address.

guess terado services will get a facelift then too? (since they require/use the 3ffe range for comms)

The most recent draft for teredo only requires use of 3FFE::/16 obliquely: 2.6 Global Teredo IPv6 service prefix An IPv6 addressing prefix whose value is XXXX:XXXX:/32. (TBD IANA; experiments use the value 3FFE:831F::/32, taken from a range of experimental IPv6 prefixes assigned to Microsoft.) Draft-huitema-v6ops-teredo-05 expired last October, and I can't find it in the I-D tracker. It doesn't seem like it would be too much of a stretch to update that section if a revision was in the works. In real life, does anybody actually use terado? Are there a well- known set of teredo servers and relays for which some arbitrary, large ISP might measure traffic levels? It seems like if it was enabled it would be possible to measure traffic from teredo's bubbles, even if nobody was actually using it to retrieve content. Joe
Ho Joe, all, The last I heard was that the draft was pending of the final step with the IESG review or something similar, but I'm not completely sure. Then IANA will assign a production prefix. I'm aware of at least 8 Teredo Relays (some of them only available within specific ASs). We run one of them, and yes, have some traffic there, so there are real users. I know at least about 2 *big* carriers which recently also have setup Teredo Servers+Relays, and some more being setup. Some of them are listed at: http://www.ipv6tf.org/using/connectivity/teredo.php Teredo is being used automatically by several applications. Some of you may haven't noticed about it, but if you are XP SP2 user its there and working some time, even if you don't enable IPv6 (Teredo gets enable by some peer to peer apps). Regards, Jordi

In real life, does anybody actually use terado? Are there a well-known set of teredo servers and relays for which some arbitrary, large ISP might measure traffic levels? It seems like if it was enabled it would be possible to measure traffic from teredo's bubbles, even if nobody was actually using it to retrieve content.
Check http://www.sixxs.net/tools/aiccu/brokers/ which has a list of most /all (send mail if you know more :) public tunnel brokers and all other related items. Only AS31701 (Consulintel) and AS5511 (OpenTransit / Wanadoo France) are announcing the 3ffe:831f::/32 prefix though. But from my logs (including ipv6gate.sixxs.net ;) I don't see any traffic coming in from it... Greets, Jeroen

Is that 5% of your IPv6 traffic, or 5% of *all* your IPv(4+6) traffic?

Not the above network, but another... I just checked the log of ipv6gate.sixxs.net (or more precise *.sixxs.org), resulting over the last day the following 6bone prefixes seem to be active (simple cut -f1,2 -d: on the address thus first 32bits) these are the only 6bone prefixes using that service: 4 3ffe:2500 92 3ffe:80ee 110 3ffe:831f 136 3ffe:4019 241 3ffe:80d0 118455 3ffe:321f 507624 3ffe:3201 3ffe::3200::/24 == CERNET The rest of 6bone is pretty dormant compared to that one. (Though they might also not be using the service of course) Then again, check the top 5 6to4 sources (also per /32): 9169 2002:d347 12281 2002:a66f 32554 2002:ca75 65035 2002:de1d 2295865 2002:a269 Take a guess what the last line is from ;) In this sample the number for 2001:<something> (RIR space, I didn't catch anything from non-2001 prefixes) is: 2371150 2001 Other wise put: ------------------------ 6to4 2414904 44.61% RIR 2371150 43.80% 6bone 626662 11.57% ------------------------ total 5412716 Still an amazing 11.57% of the hits of this traffic sample. And all coming from the same place too... Btw, note that 6to4 is only used by 1 very large user site which also has RIR space and 6bone space. Clearly for them 6to4 is very easy to use. Btw2 I am not looking at transfered bytes here, but I assume them to be mostly consistent with the hit count. Most 6bone prefixes that are still announced are dormant on the net, they are there but not used at all. Greets, Jeroen
