How to execute

#By default, ZMap will perform a TCP SYN scan on the specified port at the maximum rate possible. A more conservative configuration that will scan 10,000 random addresses on port 80 at a maximum 10 Mbps can be run as follows:

zmap --bandwidth=10M --target-port=80 --max-targets=10000 --output-file=results.csv

 

#ZMap can also be used to scan specific subnets or CIDR blocks. For example, to scan only 10.0.0.0/8 and 192.168.0.0/16 on TCP/80, run:

zmap -p 80 10.0.0.0/8 192.168.0.0/16
