ZMap is a fast single-packet network scanner optimized for Internet-wide network surveys.
By default, ZMap will perform a TCP SYN scan on the specified port at the maximum rate possible. ZMap can also be used to scan specific subnets or CIDR blocks.
On a computer with a gigabit connection, ZMap can scan the entire public IPv4 address space on a single port in under 45 minutes. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in 5 minutes.
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.
This is free and open source software.
