internet_address_history_it74w-20170222

This dataset, generated on 2017-03-29, 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 it59w to it74w.

本数据集编制于2017年3月29日，囊括了自互联网地址调查（Internet Address Survey，简称IAS）的it11w（internet_address_survey_it11w-20060307）起，直至后续的it11w、it12w等各次调查中，曾对我们的ISI-west（w）普查作出响应的所有IPv4地址。每个IP地址都附带了一份历史回复记录（以位串形式呈现，其中's'代表从该IP接收到的ICMP_ECHO_REPLY，而's'则对应无响应）。此外，我们还纳入了旨在反映给定IP地址在未来作出响应可能性的数值评分。这些评分基于从it59w至it74w的普查数据。
