Result of all IP adresse from internet 130Mb sqlite3 database.

I need this tool for free offline IP query and Mail sorting.

This app dont need SQL from QT or plugin, the small lib is build in...
Not tested on window, any error report help me..


Here the time to handle all IP adress
Update Ip adress one time at week

Querying the Database
Querying is pretty straight forward, but remember that IP Addresses are used in their integer representation).

Eg. my current IP 92.195.213.74 translates to 1556337994.

A simple lookup then looks like this:

SELECT loc.*
FROM geolocation loc,
geoblocks blk
WHERE blk.idx = (1556337994-(1556337994 % 65536))
AND blk.startIpNum < 1556337994
AND blk.endIpNum > 1556337994
AND loc.locId = blk.locId;

In case you wonder: the modulo operation there makes the lookup *much* faster. It's an optimization I found at the Maxmind website and adapted from MySQL to sqlite.

-- add additional index
-- (Tip by Kamil Kubica. https://www.maxmind.com/app/csv)
ALTER TABLE geoblocks ADD COLUMN idx INTEGER;
UPDATE geoblocks SET idx = (endIpNum - (endIpNum % 65536));
CREATE INDEX geoidx ON geoblocks(idx);
