Hazarding a very quick guess: if this table is what I think it is (NON- overlapping IP ranges + (geo)location), you might want to try: SELECT * FROM iploc WHERE start_ip < 1902800418 ORDER BY start_ip DESC LIMIT 1 ... at least, that is how we solved our geoip-performance problems. The NON- overlappig part is crucial though. -- Rik Wasmus -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
