import os
import sys
myArgs = list(sys.argv)[0:]
if len(myArgs) == 2:
	threads = int(myArgs[1])
	file = 0
	if os.listdir('.').count('nmap') == 0:
		os.system('mkdir nmap')
	if threads <= 256 and 256 % threads == 0:
		for i in range(0, 256, 256//threads):
			os.system('python3 ' + myArgs[0] + ' ' + str(i) + ' ' + str(i + 256//threads) + ' &' )
	else:
		sys.exit('Error: wrong number of threads')
	os.sync()
else:
	start = int(myArgs[1])
	end = int(myArgs[2])
	file = str(str(start) + '-' + str(end - 1) + '.nmap')
	if start == end - 1:
		file = str(str(start) + '.nmap')
	for i in range(start, end):
		os.system(str('nmap 192.168.' + str(i) + '.0/24 >> nmap/' + file))
	os.sync()

It will generate a directory with files named %.nmap in the case of 256 streams (192.168.%) and %-#.nmap in other cases (192.168.% - 192.168.#)

I would recommend to do it it the separate terminal, also 128 and 256 threads require lots of resources.

It can freeze your network
