It would be good to have a test that ensures if the first line is not 'fe:ff...', but the second line is, that the method correctly returns `true`. In other words, that it actually walks all of the entries in the table until it either finds an amazon arp or runs out of addresses. This would detect the bug that was present previously (as it only checked the first line).
