The unexplained awakening over the past four months of more than 100 million previously dormant US Department of Defense (DoD) IPv4 addresses now has
On January, 20, 2021, as noted over the weekend by Doug Madory, director of internet analysis at network monitoring biz Kentik, a sizable portion of
unused IPv4 address space registered to the DoD (GRS-DoD) and referred to as AS8003, began announcing the reachability of millions of previously
unreachable addresses via the Border Gateway Protocol (BGP).
Coming ten minutes after President Joseph Biden was sworn into office and three minutes prior to the statutory conclusion of Donald Trump's term, the
timing of the BGP announcement invited speculation about the motives for lighting up so many previously dark addresses.
More so, because the company administering the growing swath of addresses – Plantation, Florida-based Global Resource Systems LLC – lacks a
meaningful web presence and because that opacity extends to the organization's ownership.

The DoD has fourteen /8 blocks, so 243.8 million and some change minus the overhead addresses. Why they need all of those addresses is a little odd
but not unexpected. They use a tiny fraction of the addresses available to them I'm sure. Now the activity on those addresses that had since been
dormant at the time, it's pretty strange indeed.
