Every resolver implementation uses slightly different algorithms, and
typically spends much more logic dealing with errors of various sorts
than typical occurances. This section outlines a recommended basic

... count of -1, which says that the servers aren't very close to the
target. Note that the -1 isn't supposed to be an accurate closeness
measure, just a value so that later stages of the algorithm will work.
