I'm not sure there is. I'm not sure one can be truly sure he scanned the Internet before impersonating every host. Can't know anything before trying out the inside of every skin.
After all, what would you know, as a traveller, about simple lives of local people?
I've spent one hour of my life in Germany, when I was 11 years old, in a transit lounge in Frankfurt. I have 'visited Germany', but not in any real sense.
There's more to the internet than just port 80, so to declare that a scan encompassing only a single port on each host is a scan of "the entire internet" is somewhat mistaken.
The more correct title would be, "a scan of the entire World Wide Web."
"We experimentally showed that ZMap is capable of scanning the public IPv4 address space on a single port in under 45 minutes, at 97% of the theoretical maximum speed for gigabit Ethernet and with an estimated 98% coverage of publicly available hosts."
I realise that my comment was not so clear, sorry about that. Yes, to me scanning the whole internet means at least the full port range in TCP (and why not UDP too).
My 'rant' is really about the article sensational title promising to let you know about the result of scanning the entire internet really fast... wich turns out to be about scanning web services. The data is however interessting.
