Then this should work.

SELECT remote_user, substring_index(remote_host,'.',3)
 AS ip_subnet
FROM password_log LEFT JOIN exclude_log ON
substring_index(password_log.remote_host,'.',3) =
exclude_log.ip_block
WHERE remote_user != '-' AND status=200 AND
ip_block IS NULL
GROUP BY ip_subnet
ORDER BY remote_user, ip_subnet
