This doesn't work in general, because string comparison is in collating order, not the numerical values of the four fields. For instance, '1.1.2.2' > '1.1.128.1' -- the critical spot in the 5th character, '1' vs '2'.

If you want to compare the fields, try separating into lists:

ip_vals = [int(x) for x in ip_range.split('.')]

ip_vals is now a list of the values; you can compare the lists and get the results I think you want.
