If the response (ICMP_ECHO_REPLY) came, its IP address │ │ │ was recorded in this data-set. In all, over 2.5 billion distinct IP addresses were │ │ │ probed during this experiment. │

LANDER:Templates/Census/DatasetContents-v2-t Data Format Binary format of trace files is described in detail here: http://www.isi.edu/ant/traces/topology/address_surveys/binformat_description.html Collection Method Data collection involves pinging all allocated addresses. A full description of this method is in: > John Heidemann, Yuri Pradkin, Ramesh Govindan, Christos Papadopoulos, Genevieve Bartlett, and Joseph Bannister. > Census and Survey of the Visible Internet. In Proceedings of the ACM Internet Measurement Conference, p.169-182. > Vouliagmeni, Greece, ACM. October, 2008 http://www.isi.edu/~johnh/PAPERS/Heidemann08c.html. Probing Location(s) The probing locations for censuses and surveys are indicated in their names. A "w" means west, which is from isi.edu in Marina del Rey, California; "c" means center, from colostate.edu, in Ft. Collins, Colorado; "e" means east which is from east.isi.edu, from Arlington, Virginia; "j" means Japan, which is from WIDE in Fujisawa-shi, Kanagawa, Japan; "g" stands for AUEB, located in Athens, Greece; "n" stands for Utrecht, The Netherlands. See Dataset Contents for more information on the system who did the survey. Coverage Earliest censuses started before June 2007, i.e. up to and including it17, did not attempt to probe addresses with the last octet either 0 or 255, e.g. x.y.z.0 (/24 subnet address) or x.y.z.255 (/24 broadcast). Censuses started between September 2007 and June 2008, i.e. it18-it21, probed all values of the last octet, except .255. Censuses started after September 2008, starting from it22, probed all values of the last octet, including both .0 and .255. Beginning/Ending Date and Time Zone Dates/Times specified in the metadata are in UTC. Earlier censuses (before it37) used local time in their metadata description. Their metadata will be updated to effectively switch to UTC in the near future.
