NMAP continuous ping

I need to implement a code which is able to send ping packets each second toward a certain amount of destinations. The problem is that I'd like to ping as much destinations as possible inside 1 second window. For this reason I was thinking if there was a way to impose cycling into nmap [I mean something like -cycle nmap parameter] so that sockets would be opened only once and closed at the end of loop ping, saving way more time than using a "watch nmap" approach!

Part of the Nmap project is the Nping tool. It is designed to do exactly what you want, and is very configurable. Here's an example run:

$ sudo nping --rate 4 --icmp 192.168.1.4/30

You could spawn multiple parallel nmap processes in the command line via:

nmap [options for destination 0] > output0 &

Spawn many such nmap requests for each destination while keeping a running index of the outputX files (output0, output1, etc).. When all your requests are complete, you can examine the contents of each output file
