(APNIC 28 - APOPS) DITL, by George Michaelson of APNIC

An overview of the "Day in the Life of the Internet" (DITL) project, and some initial results from APNIC's participation, focusing on differences seen at our DNS services during the 2008 and 2009 collections. Emerging data from the review of APNIC's DITL contributions in 2008 and 2009 strongly suggest that "infrastructure" DNS use has more complex behaviours than previously understood, and requires further study. Initial results suggest that of a population of around 1,000,000 querying IP addresses, around 30 per cent are persisting year-on-year which is a far higher output than expected. The dynamics of how IP addresses are used to query infrastructure DNS are not what we expected.
