"select Country from GeoIP where ('$lip' > Start_int) and ('$lip' < End_int) limit 1");

Aside from adding insecurity with dynamic SQL, there's little benefit from possible RDBMS caching. That is, preparing a query that uses palceholders allows the RDBMS to create a PLAN that (it thinks) is best for varying arguments. Also, rerunning the query does not require a new prepare.

And, large loads can be done with a bulk collect.

'$lip' > Start_int) and ('$lip' < End_int)

BETWEEN is inclusive. So a BETWEEN b and c means a >= b AND a <= c. So, there's a difference between (no pun intended) the two statements.
