SHORT DESCRIPTION:

The dataset contains unique IPv4 addresses collected from
a spam list for 3-month time periods over almost 3 years, 
starting in April 2012 and ending at the end of 2014.

LONG DESCRIPTION:

Each of the files in this dataset contains the unique IPv4
addresses on a publicly available DNS blacklist during a 
3-month period. For details about the blacklist see 
http://www.dnsbl.manitu.net/

We polled the blacklist every 15 minutes and then aggregated
the data into the unique IPv4 addresses for 3-month time windows.

Predicting the Used IPv4 Space by Inferring Unobserved 
Addresses", in Internet Measurement Conference (IMC),
