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.

为构建本数据集，研究人员实施了一次全域互联网IP地址扫描活动。研究人员通过发送ICMP回声请求（ICMP ECHO_REQUEST，即PING）数据包，对互联网编号分配机构（Internet Assigned Numbers Authority, IANA）分配的全部IP地址段内的每一个IP地址开展了一次PING探测。若该IP地址返回ICMP回声响应（ICMP_ECHO_REPLY）数据包，则将其IP地址记录至本数据集。本次实验总计探测了超过25亿个独立IP地址。
