IPv6 extension headers support on RIPE Atlas
by Jen Linkova 19 Nov '13

19 Nov '13

[ This is a outcome of some online&offline discussions we have had on IETF8 ] There are some ongoing efforts to measure IPv6 extension headers filtering in the Internet (in particular, see Fernando Gont's talk: http://www.iepg.org/2013-11-ietf88/fgont-iepg-ietf88-ipv6-frag-and-eh.pdf ) While individuals are running some experiments from their networks, I think it would be extremely useful to run distributed measurements using Atlas to understand the current situation and possible impact better. Therefore it would be great if Atlas supports: - inserting Ipv6 extension headers into probe packets. Ideally user should be allowed to define a chain of extension headers as specified in RFC2460. In particular, it would be nice to insert the following headers: -- Hop-by-Hop Options -- Fragment -- Destination Options - HTTP measurements (Tim, please add particular requirements if you have any). If anyone else would like to see such features supported by Atlas - please speak up! -- SY, Jen Linkova aka Furry

Asking methods to monitor used IPs
by Jahangir Asadi 08 Nov '13

08 Nov '13

Dear Sir or Madam I have some customers who I have allocated high band width with wide ranges of IPv4 addresses to. Because of lack of IPv4, I would like to see that how many IPs they are using. It would be grateful if you tell me how can I do this and what soft ware I have to use to monitor the used IPs. I would like to thank you in advance and I am looking forward to hearing from you soon. Regards. Jahangir Asadi Network Manager of Padidar Information Technology (Your LIR Member and the owner of AS198357)

Announcing the RIPE Atlas Anchors Service
by Vesna Manojlovic 07 Nov '13

07 Nov '13

Dear colleagues, We're pleased to announce that RIPE Atlas anchors went into production at the RIPE 67 Meeting in Athens in October 2013. Anchors are both enhanced RIPE Atlas probes with more measurement capacity, as well as regional measurement targets within the greater RIPE Atlas network. The RIPE Atlas anchors pilot ran for a year, and now there are 15 anchors deployed. The RIPE NCC's goal is to have 50 anchors in operation around the world by the end of 2014. We are now actively seeking applications from those interested in and capable of hosting a RIPE Atlas anchor in their own networks. Find out what RIPE Atlas anchors are all about, the benefits of hosting an anchor, and how you can get involved: https://labs.ripe.net/Members/suzanne_taylor_muzzin/announcing-the-ripe-atl… Regards, Vesna

Re: [mat-wg] IPv6 extension headers support on RIPE Atlas

On Wed, 6 Nov 2013, Ole Troan wrote: > wouldn't it be sufficient to support the fragment header initially? I am mostly interested in extension- and fragment header, and combinations of these. The others you're right about, they probably won't work well anyhow. But extension nnd fragment headers have real legitimate use and we should try to assure that these work properly on the wider Internet. If someone at the edge decides they don't want these then that's fine, but if there are routers out there that by default treat these badly, I think it's good if everybody knows this. -- Mikael Abrahamsson email: swmike(a)swm.pp.se

Traceroute visualisation
by Mike Hughes 18 Oct '13

18 Oct '13

Good talk by Emile on visualisation of traceroutes and the various sources of geo-loc that can be munged and derived to try and give more accurate info. While there was talk of commercial geo-loc such as Maxmind, what about mining the DNS for LOC records? Has there been any investigation of that? Or am I just an ossified dinosaur, talking about LOC records? :) Cheers, Mike
