The DOD had reserved a gazillion IP4 addresses it didn't use for decades. Scammers and bad actors are probably using those addresses to mask the origins of packets or misroute data. Now those addresses are 'lit,' so a device somewhere will actually receive those packets, including info packets about bad routing, address unknown, resends, etc. If something actually examines the data received that uses these addresses, a lot of interesting information about scammers or intel agencies using these addresses might be garnered.
Or, you'd just collect gigabytes of garbage.
Both, excellent replies.
I have used wireshark to solve small problems with IP cameras.
I appreciate your explanations. I understand more.
Thank you.
