The Future of IPv6 at Grey Noise

Summary: GreyNoise reviewed IPv6 research to plan where its sensors and data collection go next, noting that IPv6 adoption is rising, the US government has set dates to migrate all government resources to IPv6, and IPv4 exhaustion continues. Because IPv6 holds roughly 340x10^36 addresses, scanning it at the rate zMap uses to cover all 4.2 billion IPv4 addresses in under an hour would take an estimated 6.523 × 10^24 years, so actors instead rely on found-address databases like the IPv6 Hitlist, which malicious actors also use to hunt vulnerable hosts.

Why it matters: The IPv6 Hitlist and similar databases of responsive addresses serve both academic researchers and attackers hunting vulnerable hosts, so where your devices appear in IPv6 space determines who finds them first.
