import sys, socket
try:
	ipLines = open('ip.txt').readlines()
	results = []
	for ip in ipLines:
		result = socket.gethostbyaddr(ip.replace('\n',''))
		results.append(result[0])
		print "Primary hostname:"
		print " " + result[0]
		print "\nAddresses:"
		for item in result[2]:
			print " " + item
	wr = open('hostname.txt','w+')
	for host in results:
		wr.write(host)
		wr.write('\n')
	wr.close()
except socket.herror, e:
