Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

my bad; language was C#.
a couple of issues with the kata - not super important; just made getting started difficult
test cases reference "IsValidIp", while the solution itself has a main method of "is_valid_IP"
parameter is spelled "ipAddres" instead of "ipAddress"
otherwise, good kata :)
after spending an embarrassing amount of time fiddling with this problem i'm laughing at myself now for missing such a simple answer. well done, friend
i ran into index errors because some of the test cases involve empty strings; this may be the case here.
this is incredibly clever
