Run this and you should see which error is being raise. Do note we
catch urllib2.HTTPError instead of IOError.
try:
req = urllib2.Request(URL % ips[1])
handle = urllib2.urlopen(req)
print 'Success'
print handle.getcode()
print handle.headers
except urllib2.HTTPError as e:
print 'Exception caught'
print e
print e.getcode()
print e.hdrs
