Ping a range of IP addresses using Python (or whatever else you need to do)

#!/usr/bin/env python
# IPRange. Do stuff with IP addresses.
# this is code is designed to parse a range of ip addresses and
# do something with them. Example uses are ping, nmap, ssh, etc.
# have fun, but don't do illegal things and if it breaks everything
# around you it isn't my fault. Use this only for good, not evil.
# contact author(Sam Levine):
# host = darkscyon
# domain = (you know, google mail)
# no spam or complaints please. patches are welcome. feedback
# (good or bad) is very welcome.
# Be excellent to one another.
