Thank you for your thoughtful suggestion. Please see my above post for "show create table" output. The query you suggest here does indeed run fast, but I don't think the output is correct. All three assumptions you list do indeed hold. But that query always matches the first row of table range, since the only condition is that the address be greater than or equal to the floor of the range (begin_num).
