>> This is what I was trying but LooseVersion() was not sorting version numbers like I thought it would. You will notice that Chrome version "40.0.2214.111" is higher than "40.0.2214.91" but in the end result it's not sorting it that way.

Also, Python 3.4 comes with an ipaddress module.

>>> import ipaddress
>>> address_string_1 = "2.2.3.4"
>>> address_string_2 = "10.2.3.4"
>>> address_string_2 > address_string_1
False
>>> ip_address_1 = ipaddress.ip_address(address_string_1)
>>> ip_address_2 = ipaddress.ip_address(address_string_2)
>>> ip_address_2 > ip_address_1
True
