We are working in bits, use bits instead, that will avoid theses kinds of mistakes.

Oh yeah sorry I misunderstood it, yeah it's pretty unlikely that you would get 1 url for a prefix(but still possible). I would have to get out my old probability books to find that out but it's not worth it, the probability would be way too tiny.

I thought it was about certainty to be able to match it with the real URL. In theory it would takes only a few page hit to be certain of the domain and thus the URL (if there's no unknown string in the URL).
