hi folks, many of you have already heard about it, but we want to remind folks of the 'day in the life of the Internet' 2008 experiment: we're coordinating dns (and possibly other types of) measurements from a single (2)day period in mid-march 2008. we will repeat our simultaneous root server collections from 2007, and try to expand our coverage to include other TLDs, and hopefully data from other levels of the hierarchy, e.g., caching resolver data. we'd also like to compare statistics from secured vs unsecured zones. we're hoping this experiment provides data to help answer questions operators care about, e.g., IPv6 adoption, DNSSEC adoption, pollution to root servers, use of unallocated addresses in the wild, reverse DNS deployment, <send us your questions> (working list at: http://www.caida.org/projects/ditl/questions/ ) OARC is providing special support for this project, and Duane is executing some practice runs with participations this week, to test measurement/transport logistics. DNS-based participation should not require much work, ideally running 'dnscap' on/near DNS server(s) and sending the pcap files to OARC: (public.oarci.net) but there are other methods of participation too, depending on your policy constraints. (indexing data into datacat and controlling distribution of the data through your own AUP, or submitting more "cooked" data, e.g., logfile summaries, RRD graphs, reports based on data collected internally by networks during the DITL dates. if you are interested in donating the time and energy and (some form of) data to this project, please let duane, kenjiro, or me know and we'll get you started.
