None of these are hard and fast rules -- the protocol is designed to work
with any mix -- but to the degree that you can keep similar numbers
together (similar in this case meaning they share the first "n" digits)
you can keep the number of queries down for irrelevant questions.
Another option, if you have only a few numbers, is to use the new
"PRECACHE" stuff which essentially works by pushing your routes up to the
next tier -- essentially an unsolicited answer, and then not having to
receive queries. This can be a good option for someone with few distinct
routes (I still have to get patterns supported though!).
