route6: 2A00::/12

[Manish Karir]

Hi Antonio,

Here is some related material:

Internet Pollution Studies in IPv4:

- 1/8 Pollution NANOG Presentation: http://www.merit.edu/research/pdf/2010/karir_1slash8.pdf

- Follow on: NANOG Presentation: http://www.merit.edu/research/pdf/2011/Internet-Pollution-Part2.pdf

- IMC Paper on Internet Pollution: http://www.merit.edu/research/pdf/2010/imc10-wustrow.pdf

A recent workshop on the topic: http://www.caida.org/workshops/dust/1205/

Internet Pollution in IPv6:

- Geoff Hustons work on IPv6 darknets: http://www.caida.org/workshops/dust/1205/slides/dust1205_ghuston.pdf

- Details of APNICs experiment with announcing their IPv6 cover /12 route as well as analysis of results:  http://www.caida.org/workshops/dust/1205/slides/dust1205_cdeccio.pdf

This particular effort is an attempt to replicate the work performed by Geoff Huston at APNIC for different regions in order to understand any regional 
variations that might exist.  
In general we collect all un-wanted traffic in the darknet of our experiment.  Our general experiment architecture is shown here: http://software.merit.edu/darknet
Results from our analysis are presented back into the Internet operations community along with any recommendations that might emerge.  Data collected is shared
with researchers at the RIRs for their own analysis.

Please let me know if you have additional questions.

Thanks.
