DoD has “massive ranges” of IPv4 space

The Defense Department "was allocated numerous massive ranges of IPv4 address space" decades ago, but "only a portion of that address space was ever utilized (i.e. announced by the DoD on the Internet)," Madory wrote. Expanding on his point that the Defense Department may want to "scare off any would-be squatters," he wrote that "*there is a vast world of fraudulent BGP routing *out there. As I've documented over the years, various types of bad actors use unrouted address space to bypass blocklists in order to send spam and other types of malicious traffic."

On the Defense Department's goal of collecting "background Internet traffic for threat intelligence," Madory noted that "there is a lot of background noise that can be scooped up when announcing large ranges of IPv4 address space."
