4 possible explanations for why a mysterious Florida company is managing a huge chunk of Pentagon internet addresses, according to cybersecurity experts gkay@businessinsider.com (Grace Kay) Moments before the inauguration, a Florida company began managing nearly 175 million Pentagon IP addresses. The Department of Defense said it is using the addresses to "identify vulnerabilities" in DoD space. Here are four possible explanations for the Pentagon's decision, according to cybersecurity experts. What's more, the deal was announced about three minutes before former US president Donald Trump left office and it encompasses almost 6% of usable internet space. It is largely unknown what the Pentagon is planning to do with the IP addresses, as well as why the government chose the unknown startup, Global Resource Systems LLC. Cybersecurity experts told Insider the Pentagon could be looking to do anything from lure in hackers and build up online government defenses to surveillance of US citizens and reconnaissance on foreign countries.
