Further analysis and time series graphs of this data
are available at
SpamRankings.
"Listings" is the number of unique IPs at the corresponding asntraffic
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
asntraffic 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).
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 most are 2009.
IPop%: Percentage of Internet users that are infected.
