internet_address_history_it44w-20111102

This dataset, generated on 2011-12-07, contains all IPv4 addresses who ever responded to our ISI-west (w) censuses, starting from census it11w (internet_address_survey_it11w-20060307), e.g. it11w, it12w, ... Each IP address is given a history of replies (as a bit-string with 's representing ICMP_ECHO_REPLY received from this IP, and 's corresponding to no-replies. We also include numerical scores that are intended to reflect the likelihood that the given IP address will repond in the future. The scores are based on census data from it29w to it44w.

本数据集创建于2011年12月7日，囊括了自census it11w（互联网地址调查_it11w-20060307）以来，曾对ISI-west（w）普查作出响应的所有IPv4地址，例如it11w、it12w等。每个IP地址均附有回复历史（以位串形式表示，其中's代表从该IP收到的ICMP_ECHO_REPLY，而's则对应无响应）。此外，我们还包含了旨在反映特定IP地址未来响应可能性的数值评分。这些评分基于从it29w至it44w的普查数据。
