internet_address_census_it84w-20190130 (2019-01-30 to 2019-03-03)

To collect this data, an Internet-wide IP address sweep was conducted. Every IP address in the ranges allocated by IANA was pinged once by sending ICMP ECHO_REQUEST (PING) packet. 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.本数据集的采集方式为：开展全球范围的互联网IP地址扫描工作，对互联网编号分配机构（Internet Assigned Numbers Authority, IANA）分配的所有IP地址段内的每个IP地址，均发送一次ICMP回声请求（ICMP ECHO_REQUEST，即PING）数据包。若成功接收到对应的ICMP回声应答（ICMP_ECHO_REPLY），则将该IP地址记录至本数据集。本次实验中共探测了超过25亿个独立IP地址。
