import - Importing MaxMind's GeoLite2 to MySQL

Question

MaxMind's GeoLite2 is a wonderful database and is very useful if you want to map IP addresses to countries.

To do this efficiently, I want to import it into a MySQL database with a scheme like this:

I remember writing an import script for the CSV database long time ago, but the CSV as you can download it today has a very difficult to understand format, at least to me:

network,geoname_id,registered_country_geoname_id,represented_country_geoname_id,is_anonymous_proxy,is_satellite_provider 1.0.0.0/24,2077456,2077456,,0,0 1.0.1.0/24,1814991,1814991,,0,0 1.0.2.0/23,1814991,1814991,,0,0 1.0.4.0/22,2077456,2077456,,0,0 1.0.8.0/21,1814991,1814991,,0,0 1.0.16.0/20,1861060,1861060,,0,0 1.0.32.0/19,1814991,1814991,,0,0 1.0.64.0/18,1861060,1861060,,0,0 1.0.128.0/17,1605651,1605651,,0,0

I'm really stuck at the basics here. What is the most efficient and easiest way to import the database from its CSV representation into MySQL?

Answer 1

network,geoname_id,registered_country_geoname_id,represented_country_geoname_id,is_anonymous_proxy,is_satellite_provider
1.0.0.0/24,2077456,2077456,,0,0
1.0.1.0/24,1814991,1814991,,0,0
1.0.2.0/23,1814991,1814991,,0,0
1.0.4.0/22,2077456,2077456,,0,0

create table thing1
(   network varchar(20) not null,
    geoname_id varchar(20) not null,
    registered_country_geoname_id varchar(20) not null,
    represented_country_geoname_id varchar(20) not null,
    is_anonymous_proxy varchar(20) not null,
    is_satellite_provider varchar(20) not null
);

LOAD DATA INFILE 'c:\dev\ipaddr.txt' 
INTO TABLE thing1
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '
'
IGNORE 1 LINES
(@v1,@v2,@v3,@v4,@v5,@v6)
set network=ifnull(@v1,''),
geoname_id=ifnull(@v2,''),
registered_country_geoname_id=ifnull(@v3,''),
represented_country_geoname_id=ifnull(@v4,''),
is_anonymous_proxy=ifnull(@v5,''),
is_satellite_provider=ifnull(@v6,'');

The above came in fine for me.

Begin of Edits below

For the below, attempting to improve this answer after points made by stijn-de-witt in comments.

Note however that the referenced blog in the comments had an error in the update statement for going into ints. So for the time being until I sort that out, I found a varchar modification as seen below.

Edit1 (more to follow, see comments below answer):

Alter the table to get a "from ip to ip range"

alter table thing1 add column from_ip varchar(20), add column to_ip varchar(20);
-- note that those two are nullable at the moment. You can always change that later

Update table for the varchar's just added

update thing1
set from_ip=  INET_NTOA(INET_ATON( SUBSTRING_INDEX(network, '/', 1)) 
   & 0xffffffff ^ ((0x1 << ( 32 - SUBSTRING_INDEX(network, '/', -1))  ) -1 )),
to_ip=   INET_NTOA(INET_ATON( SUBSTRING_INDEX(network, '/', 1)) 
   | ((0x100000000 >> SUBSTRING_INDEX(network, '/', -1) ) -1 ))
select * from thing1;

(For the above update statement, Credit to Bernd Buffen in this answer )

Results of the above update statement:

mysql> select network,from_ip,to_ip from thing1;
+------------+---------+-----------+
| network    | from_ip | to_ip     |
+------------+---------+-----------+
| 1.0.1.0/24 | 1.0.1.0 | 1.0.1.255 |
| 1.0.2.0/23 | 1.0.2.0 | 1.0.3.255 |
| 1.0.4.0/22 | 1.0.4.0 | 1.0.7.255 |
+------------+---------+-----------+

From here, check out the MySQL Manual Page Miscellaneous Functions for INET_ATON(expr).

Edit2 (thanks to stijn-de-witt again):

alter table thing1 add column uint_from_ip int unsigned, add column uint_to_ip int unsigned;

UPDATE thing1 SET uint_from_ip = inet_aton(SUBSTRING(network, 1, LOCATE('/', network) - 1)), 
uint_to_ip = (inet_aton(SUBSTRING(network, 1, LOCATE('/', network) - 1)) + (pow(2, (32-CONVERT(SUBSTRING(network, LOCATE('/', network) + 1), UNSIGNED INT)))-1));

Results:

select network,from_ip,to_ip,uint_from_ip,uint_to_ip from thing1;
+------------+---------+-----------+--------------+------------+
| network    | from_ip | to_ip     | uint_from_ip | uint_to_ip |
+------------+---------+-----------+--------------+------------+
| 1.0.1.0/24 | 1.0.1.0 | 1.0.1.255 |     16777472 |   16777727 |
| 1.0.2.0/23 | 1.0.2.0 | 1.0.3.255 |     16777728 |   16778239 |
| 1.0.4.0/22 | 1.0.4.0 | 1.0.7.255 |     16778240 |   16779263 |
+------------+---------+-----------+--------------+------------+
