I was so excited to use a stack too 😂

same here, i spent 2 hours on this and my solution was 70 lines of code 🤣

See this It seems you forgot to change the initial code function's name.

my bad; language was C#.

Please mention the language that has the problem.

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
