Third Workshop on Internet Economics (WIE2012)

Friday, April 19th, 2013 by kc

As part of our NSF-funded network research project on modeling Internet interconnection dynamics, David Clark (MIT) and I hosted the second Workshop on Internet Economics (WIE2012) last December 12-13. The goal of the workshop was to provide a forum for researchers, commercial Internet facilities and service providers, technologists, economists, theorists, policy makers, and other stakeholders to empirically inform emerging regulatory and policy debates. The theme for this year’s workshop was “Definitions and Data”. The final report describes the discussions and presents relevant open research questions identified by workshop participants. Slides presented at the workshop are available at the workshop home page. From the intro (but the full report (6-page pdf) is worth reading):

Correlation between country governance regimes and the reputation of their Internet (IP) address allocations

Monday, April 15th, 2013 by Bradley Huffaker

[While getting our feet wet with D3 (what a wonderful tool!), we finally tried this analysis tidbit that’s been on our list for a while.]

We recently analyzed the reputation of a country’s Internet (IPv4) addresses by examining the number of blacklisted IPv4 addresses that geolocate to a given country. We compared this indicator with two qualitative measures of each country’s governance. We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses.
