geolite2legacy

This tool will convert MaxMind GeoLite2 Database to the old legacy format.

It's based on mmutils but it reads new GeoLite2 directly from zip files containings CSV databases.

You can download databases from https://dev.maxmind.com/geoip/geoip2/geolite2/

It's tested with python/pypy 2.7 and python 3.5+

Limitations

  • Processing may be slow, expecially for City blocks, consider using pypy, it is a lot faster
  • Some software may expect iso-8859-1 encoded names, but the script will output utf-8, you can force a different encoding e.g. using -e iso-8859-1 but some name may result wrong

Examples

$ ./geolite2legacy.py -i GeoLite2-Country-CSV.zip -f geoname2fips.csv -o GeoIP.dat
Database type Country - Blocks IPv4
wrote 306385-node trie with 300679 networks (251 distinct labels) in 8 seconds

# ./geolite2legacy.py -i GeoLite2-ASN-CSV.zip -o GeoIPASNum.dat
Database type ASN - Blocks IPv4
wrote 518484-node trie with 417952 networks (62896 distinct labels) in 15 seconds

Usage

usage: geolite2legacy.py [-h] -i INPUT_FILE -o OUTPUT_FILE [-f FIPS_FILE]
                         [-e ENCODING] [-d] [-6]

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT_FILE, --input-file INPUT_FILE
                        input zip file containings csv databases
  -o OUTPUT_FILE, --output-file OUTPUT_FILE
                        output GeoIP dat file
  -f FIPS_FILE, --fips-file FIPS_FILE
                        geonameid to fips code mappings
  -e ENCODING, --encoding ENCODING
                        encoding to use for the output rather than utf-8
  -d, --debug           debug mode
  -6, --ipv6            use ipv6 database

Run inside Docker container

  1. Build the Docker image:
docker build -t geolite2legacy .
  1. This command assmes that you have downloaded the GeoLite2 database to the current directory.
docker run -it -v $(pwd):/src geolite2legacy:latest -i /src/GeoLite2-Country-CSV.zip -o /src/GeoIP.dat
