Why use PeeringDB?
by Chris Grundemann 18 Jul '12

18 Jul '12

Peering Experts, I am currently working on a BCOP for IPv6 Peering and Transit and would very much appreciate some expert information on why using PeeringDB is a best practice (or why its not). All opinions are welcome, but be aware that I plan on using the responses to enhance the document, which will be made publicly available as one of several (and hopefully many more) BCOPs published at http://www.ipbcop.org/. Also, if there are those among you who would like to review the entire document and perhaps volunteer as a SME to help expand and polish it, please contact me off-list and I'll get you a current draft. Thanks in advance. Cheers, ~Chris -- @ChrisGrundemann http://chrisgrundemann.com

Managing free pairs to prevent DSL sync. loss
by Anurag Bhatia 17 Jul '12

17 Jul '12

Hello everyone. I am having some very bad time due to my ISP's poor last mile (in India). DSL is loosing sync. consistently and this time problem seems quite interesting so I though to ask how ISPs across world managing it. Problem is high attenuation & low SNR because of "lot of free pairs" in the cable. My connection is coming from something like 100 pair > 50 pair > 20 pair > 5 pair. Now 100 pair has less then 30 active lines but based on testing it seems like at 100 pair DP there's very low noise and everything is pretty good (usual BSNL pillars in India have 100 pair terminations). Next 20 pair has just 4 active lines (and 16 free lines causing issues for those 4 working lines) and at the end my line comes from 20 > 5 with only one (which is my) line active on one of 5 pairs. Now argument of my ISP (BSNL) is that due to excessive number of free pairs, they are causing huge noise and they likely need to reduce these DP's by putting 1-2 line wire from my home till 100 pair pillar termination (which is down in other street and so needs effort in digging and putting new wire). But I just never heard about this problem anywhere else. Do DSL providers really suffer due to free pairs? Assuming other pairs are all crossed/shorted, can they still produce significant noise in other working lines? Also, what exactly was "bonding" used by AT&T in US? I thought it was actually making use of free pairs, bonding them together and having more bandwidth for end user, isn't it? If someone can pass me some detailed whitepaper or document explaining about this noise, it will be very much helpful. Thanks. -- Anurag Bhatia Web: anuragbhatia.com Skype: anuragbhatia.com Linkedin <http://in.linkedin.com/in/anuragbhatia21> | Twitter<https://twitter.com/anurag_bhatia>| Google+ <https://plus.google.com/118280168625121532854>

NAT66 was Re: using "reserved" IPv6 space

NAT was a necessary evil for IPv4 address > conservation. It has no good use in IPv6. NAT is good for getting the return traffic to the right firewall. How else do you deal with multiple firewalls & asymmetric routing? Yes, it's possible to get traffic back to the right place without NAT. But is it as easy as just NATing the outbound traffic at the firewall? Lee

IPv6 Toolkit v1.2: Latest snapshot, and git repo
by Fernando Gont 16 Jul '12

16 Jul '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, I've posted a snapshot (tarball) of my working copy of the IPv6 toolkit. The tarball is available at: <http://www.si6networks.com/research/ipv6-toolkit-v1.2.tar.gz> Additionally, I've created a git repository for the toolkit, such that collaboration is improved. The git repo is available at: <https://github.com/fgont/ipv6-toolkit.git> If you have access to a Mac OS box, please try to compile the tools, and let me know if you find any errors (or let me know if they compiled cleanly). If you can also run the tools according to some of the examples in the manuals (and report any problems), that would be great, too. P.S.: If you've sent patches and your patches have not yet been applied, most likely it just means that I'm catching-up with them (feel free to resend!). Thanks!

So I sent an email over a week ago to ipv6req(a)networksolutions.com - and since I've only recieved the auto reply. A year or so ago I did this and got very quick turnaround, but now just dead air (sent another email yesterday). Wanted to see if others had the same results (recently) and any advice before I call into phone tree hell.

All it takes is one USB stick left out in the parking lot for an employee.. By the time they get enough access to do an 'ifconfig', rest assured that they can see the NDP/ARP tables and all the traffic on that network segment as well.

CloudFlare IPv6 BGP announcements - WTF guys?
by Oliver 14 Jul '12

14 Jul '12

So, doing a "sh bgp ipv6 uni 2400:cb00::/32 long" reveals that CloudFlare are currently announcing a bunch of /48s to the rest of the internet through nLayer only - as far as I can see. Simple suggestion: announce the /32 to the internet from all peering points like good Netizens and then announce your /48s from whatever peering it is you want the traffic sent to and tag it with the NO_EXPORT community attribute so you're not spamming up everyone's tables or hoisting yourselves by your own petard by getting filtered out. Kind Regards, Oliver
