Executive summary \r\n \r\n \r\n Akamai researchers in collaboration with the Max Planck Institute for Informatics have completed the first empirical study of large-scale vulnerability scanning in the IPv6 space and have compiled their findings. \r\n \r\n The findings confirm that scanners have started sweeping the IPv6 space. Scanning the IPv6 space is vastly more complicated than scanning IPv4, and thus scanning activity in IPv6 is still rare when compared with the scanning activity in IPv4. \r\n \r\n Scan traffic is heavily concentrated among a small number of active sources; geographically, the two most active sources are scanning from China. Looking at the top networks sourcing scan traffic, there are also scans conducted by cybersecurity companies and scans executed from cloud provider address space.…
