Washington Post article that mentions Nmap

They used a tool called ZMap [1,2] by some researchers in University
of Michigan:

"ZMap is an open-source network scanner that enables researchers to
easily perform Internet-wide network studies. With a single machine
and a well provisioned network uplink, ZMap is capable of performing a
complete scan of the IPv4 address space in under 45 minutes,
approaching the theoretical limit of gigabit Ethernet."

The comparison to Nmap ITFA is very unfair. Seems this just does a
simple 1 port scan of /0. EFF's 2-3 month scan [3] was on a 100Mb link
and scraped for SSL certificates.
