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 5 minutes, approaching the theoretical limit of ten gigabit Ethernet.

On a typical desktop computer with a gigabit Ethernet connection, ZMap is capable scanning the entire public IPv4 address space in under 45 minutes. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in under 5 minutes.

"Consequently, we attempt to send probes as quickly as the source’s NIC can support, skipping the TCP/IP stack and generating Ethernet frames directly."
"ather than tracking connection timeouts, ZMap accepts response packets with the correct state fields for the duration of the scan, allowing it to extract as much data as possible from the responses it receives. To distinguish valid probe responses from background traffic, ZMap overloads unused values in each sent packet, in a manner similar to SYN cookies"
