sqlite-maxminddb
This SqLite extension provides asn() org() cc() functions for lookup ASN, CountryCode from IP adresses.
`ipmask(), ip6mask()' help to translate to prefixes easily.
Usage
-
prepares libmaxminddb install from package system, or build from source.
-
downloads geolite2 (its one of available contents) put $HOME/.maxminddb/
(on Windows) to %HOMEPATH%.maxminddb\
$ make
$ LD_PRELOAD=libmaxminddb.so sqlite3
sqlite> .load ./maxminddb
sqlite> select asn('8.8.8.8'), org('8.8.8.8'), cc('8.8.8.8');

sqlite> select asn('192.168.1.1'), org('192.168.1.1'), cc('192.168.1.1');
||
sqlite> select ipmask('192.168.1.1', 24);
192.168.1.0
NOTE
-
This extension depends on GeoIP2-Lite, or it is other way to create a custom MaxMind DB File.
-
It will process no error in the case of success IP lookup and failure getting value. Unresolveble IP is usual.
-
This extension loads mmdb file from fixed directory. I'd like to consider better way to load any mmdb file to library.
-
It is useful to write '.load /pathto/maxminddb' into $HOME/.sqliterc.
-
Although maxmind/libmaxminddb is available on Windows/OS X, I don't cater for them. Now I only check on x86_64 on ubuntu 16.
-
Update for Windows tentatively. Error message doesn't print correctly.
copy sqlite3.h, sqlite3ext.h from SQLITE3 site on same directory.
clone libmaxminddb on same directory.
run build.bat, then maxminddb.dll will be generated.
