资源简介：
This group of datasets consists of all Internet-wide sweeps, mostly using PING packets (ICMP_ECHO_REQUEST). All allocated IPv4 addresses are probed once and timestamp, response, and ttl are recorded. USC/ISI continues to collect this data several times a year and add more datasets to this group.
