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.

为采集本数据集，研究人员实施了一次全域互联网IP地址扫描行动。本次扫描覆盖互联网编号分配机构（Internet Assigned Numbers Authority, IANA）分配的全部地址段，对其中每一个IP地址均发送一次ICMP回声请求（PING）数据包以执行Ping探测。若成功接收到对应的ICMP回声回复（ICMP_ECHO_REPLY）响应，则将该IP地址记录入本数据集。本次实验总计探测了超过25亿个独立IP地址。
