ZMap: The Internet Scanner
ZMap is a fast single packet network scanner designed for Internet-wide network
surveys. 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.
ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap currently has fully implemented
probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a
large number of UDP probes.
If you are looking to do more involved scans, e.g.,
banner grab or TLS handshake, take a look at ZGrab,
ZMap's sister project that performs stateful application-layer handshakes.
