Correlation between governance and reputation of IP allocations
http://www.caida.org/research/policy/country-level-ip-reputation/ 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. NZ at the edge of the graph (CPI: very clean) but has a slightly higher fraction of spamming hosts than Australia.
On this note, has anyone had success with integrating a geo-ip lookup on incoming email for input into spam detection? Regards, Joel van Velden On 16/05/2013 6:30 a.m., Matthew Luckie wrote:
