Where does v come from?

The fact that the OP asked about what to do with the the other 65526
values suggests that he only wanted to use intervals to fill in the
gaps between meaningful values (thus having complete coverage over the
16-bit integer range).  An interval tree would not be a good approach
for that situation.
