Dear Colleagues, Since the launch of RIPE Labs at RIPE 59 in Lisbon earlier this month, a lot of new and interesting content has appeared on the RIPE Labs site. With articles covering a wide range of subjects, there is probably something interesting for everyone! - Some of you might have seen the tool to measure lameness in DNS Shane Kerr presented at the RIPE Meeting. He has kindly published the tool here: http://labs.ripe.net/node/75 - Tom Vest has written an article comparing the work of the 2009 Nobel Prize winners with the IP address allocation structure, “The Challenge of IP Addressing and the 2009 Nobel Prize”: http://labs.ripe.net/node/81 - APNIC has been an active participant in the "Day In the Life" data collection activities organised by OARC and CAIDA. George Michaelson presented the results at RIPE 59, and has now also published them on RIPE Labs: http://labs.ripe.net/node/78 - The Resource Explainer (REX) was launched at RIPE 59 as part of RIPE Labs. As a follow-up, Emile Aben, of the RIPE NCC Science Group, has looked into how REX can help to find data on the correlation between specific netblocks and spam activity: http://labs.ripe.net/node/85 - Last but not least, Rene Wilhelm has looked at the question of when a particular address block can be considered to have been routed globally: http://labs.ripe.net/node/47 There is more to come, so stay tuned! And we also encourage you to participate in the RIPE Labs forums - join in the community conversation, and let us know if we're heading in the right direction! Kind Regards, Mirjam Kühne
