CBL breakdown by Domain, Highest by count

Date prepared: Sun Feb 7 08:14:20 2016 UTC/GMT

Definition of ASN from Wikipedia and RFC1930 section 3:

Within the Internet, an autonomous system (AS) is a collection of connected Internet Protocol (IP) routing prefixes [blocks of IP addresses] under the control of one or more network operators on behalf of a single administrative entity or domain that presents a common, clearly defined routing policy to the Internet.

An ASN is the identifier used to identify one of these collections. Generally speaking, large organizations on the Internet (such as Google or Yahoo) will own one or more AS, and thus have one or more ASNs. Most smaller organizations lease IP address space within a larger AS.

Notes:

  • Further analysis and time series graphs of this data are available at SpamRankings.
  • "Listings" is the number of unique IPs at the corresponding domain which 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 domain 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).
  • IP -> ASN mapping is done using routeviews.
  • ASN -> country, domain mapping is done with the RIR allocation maps plus CBL-developed mappings.
  • 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 (only in per-capita metrics): Total number of Internet users (country statistics only). Per-country statistics obtained from The CIA World Fact Book and Wikipedia, most are 2012.
  • IPop% (only in per-capita metrics): Percentage of Internet users that are infected.
