To collect this data, all allocated and responsive Internet IP address blocks were pinged by sending ICMP ECHO_REQUEST (PING) packet. The block status was recorded in this data set. Probe was repeated every 11 minutes, and more quickly when uncertain about block status. In all, approximately 3.5M /24 subnets were periodically probed.为采集本数据集，研究人员向所有已分配且可响应的互联网IP地址块发送网际控制报文协议回声请求（ICMP ECHO_REQUEST，即PING）数据包以执行PING探测，并将各地址块的状态记录于本数据集中。探测任务每11分钟重复执行一次，当对某地址块的状态存在疑问时，则加快探测频率。总计，约350万个/24子网被周期性探测。
