You probably meant "20 bytes" here, since that's the output buffer size for this test.

Yes, was playing with 10 bytes but that bit me somewhere else. will fix.

Since this can come from the outside I'd assert that it's equal to 2. If we have no split (len(p) == 0) this will panic down below.

I don't think that len(p) can ever be zero unless you specify 0 as the last argument. If the split string isn't found you get host back.
