#2> Once again as a final note: your corporate network may be using the formerly unused DoD space internally, and if so, there is a risk you could be leaking it out to a party that is actively collecting it. How could you know? Using Kentik’s Data Explorer, you could quickly and easily view the stats of exactly how much data you’re leaking to AS8003 (now AS749). May be worth a check, and if so, start a free trial of Kentik to do so.
Not that I don't appreciate the free trial offer. But before getting into data characteristics, I'm curious which addresses should be examined in a cursory internal look-see?

#4> The message above has a timestamp of 16:57 UTC (11:57am ET) on January 20, 2021, moments after the swearing in of Joe Biden as the President of the United States and minutes before the statutory end of the administration of Donald Trump at noon Eastern time.
The questions that started to surface included: Who is AS8003? Why are they announcing huge amounts of IPv4 space belonging to the U.S. Department of Defense? And perhaps most interestingly, why did it come alive within the final three minutes of the Trump administration?
From the linked article on top, as background info. Quite interesting.

#6> However, despite the new origin (AS749) these prefixes are still routed exclusively through Hurricane Electric (AS6939)
sounds pretty familiar.

If you're going to look for one such risk you might as well look for them all - if it's public space and you don't own it you should get off it regardless what isn't advertised on the internet today.

#10Not a popular idea here, but IPv6 folks.
Even for k8s, even for your internal stuff.
