What is the purpose of running this Python script?

import subprocess

cmdping = "ping -c1 10.10.10."

for x in range (2,255): p = subprocess.Popen(cmdping+str(x), shell=True, stderr=subprocess.PIPE)

while True: out = p.stderr.read(1) if out == '' and p.poll() != None: break if out != '': sys.stdout.write(out) sys.stdout.flush()
