HN Theater has aggregated all Hacker News stories and comments that mention Christiaan008's video "DEFCON 16: Nmap: Scanning the Internet".
Youtube Summary
Speaker: Fyodor, Hacker, Insecure.Org

The Nmap Security Scanner was built to efficiently scan large networks, but Nmap's author Fyodor has taken this to a new level by scanning millions of Internet hosts as part of the Worldscan project. He will present the most interesting findings and empirical statistics from these scans, along with practical advice for improving your own scan performance. Additional topics include detecting and subverting firewall and intrusion detection systems, dealing with quirky network configurations, and advanced host discovery and port scanning techniques. A quick overview of new Nmap features will also be provided.

That reminds me of this talk I heard a while back (I think this is it: https://youtu.be/Hk-21p2m8YY)

The guys working on nmap scanned the entire Internet. That set off some serious alarms because on the target side, it looked like they were aware of the existence of the relationship between IPs/assets that were classified. If memory serves some dudes in black suits showed up at their door lol

I don't think the MiB showed up but they got some very aggressive mail from people who got scanned.

I heard a similar story at a university I once worked. They did some kind of one-off portscan in the early internet days (with blessing of the local providers whose range was scanned). Some local companies got really angry because they spent a lot of time investigating the source.
Agreed, if you want to scan the entire internet, you better be someone like fyodor, and even then the authorities will probably come a knocking. https://www.youtube.com/watch?v=Hk-21p2m8YY
