I recently wrote a script that takes IPs on the command line and returns 
their hostnames. It is enclosed below. It has little error checking.
Feel free to improve on it if you wish:
import sys
import socket;
for x in sys.argv[1:]:
    try:	
     s = socket.gethostbyaddr(x)[0]
    except:
     print x + ' not found'
     continue
    print x+': '+s
