You are trying to sort a tuple that contains
a single key,value pair. The key is an IP address
represented as a string and the value is an integer.
How do you expect those two values to sort?
Hint: Try it at the >>> prompt.

And having attempted to sort them you do nothing
with the result.

What are you trying to do with the sort?
