I'm not sure I understand it correctly. Is ip a string? If it doesn't, my
reply won't make sense :).

Now that string looks just like Python code, doesn't it? If you just eval()
such a structure, it should automatically be turned into a tuple of tuples
in one line of code.

The other solution is to use split() to split at '"),("' - this will split
all but the first and last IP in the resulting list. Then strip the leading
'(("' of the first IP and the trailing '"))' in the last IP of the
resulting list. It's a few extra lines of code.

I don't know more about this, but the options above should be enough even
if there is no smarter way of getting the data.
