In `blocks` i have start_ip_num and end_ip_num as "int(10) unsigned not null" instead of big ints; I've also got start_ip_num as the primary key, with end_ip_num as a unique key. loc_id is the same... Take the query for a melbourne ip address: select loc_id from blocks where start_ip_num >= 3405775035 and end_ip_num <= 3405775035 Lookup time went from approx 0.90 seconds to 0.00 seconds. =) Thanks for the post. =)
