good point!

in fact, it's failed with sample test for below case:

 should test that 123.045.067.089 is uncorrect

and it accepted IPv6 address according to https://golang.org/pkg/net/#ParseIP

yeah, you're right. I found a defect in my code. And all passed now after fix it. Thanks.

Nothing broken. Look at the top of the page and see how many people passed the Go kata. Cheers.

This kata also appears broken in Golang. I did pass all sample test but failed basic or random tests after I click attempt. I can't see any logical issue in my code.
