CBL breakdown by Country, Highest by count

Date prepared: Wed Oct 1 14:28:09 2014 UTC/GMT

Notes:

  • Further analysis and time series graphs of this data are available at SpamRankings.
  • "Listings" is the number of unique IPs at the corresponding country have been listed as infected by the CBL over the past 10 days.
  • "Traffic" is the number of emails that the CBL-listed IPs have sent to one (of our many) spamtrap in the past 3 days.
  • The entries prefixed by "C_" are where the country isn't known, and thus the entry consists of the ASN the entries belong to. These entries will be corrected as time permits.
  • AS?? entries are whether a routeviews lookup failed to resolve the IP to an AS number (needed to identify country and domain).
  • For one comparison of effectiveness, see Jeff Makey's current DNSBL comparison page

  • IP -> ASN mapping is done using routeviews.
  • ASN -> country, domain mapping is done with the RIR allocation maps plus a proprietary database which chooses to remain anonymous.
  • Traffic statistics: These are numbers taken at just one spamtrap, and does not represent the total flow. It is perhaps more an indicator of what a medium sized site would "see", than the entire CBL detection array.
  • Size(K): Approximate total IP addresses assigned to this entity in K. Eg 747 corresponds to 764928 IP addresses - approximately 12 /16s.
  • Infect %: Percentage of allocation that is listed. For example, at time of writing, the Infect % of IN is 6.118%, meaning 6.118% of all IN-allocated IPs are CBL-listed.
  • IPop: Total number of Internet users (country statistics only). Per-country statistics obtained from The CIA World Fact Book and Wikipedia, most are 2012.
  • IPop%: Percentage of Internet users that are infected.
