IP Location To MMDB

This is simple CLI tool to convert any of the CSV datasets from the excellent ip-location-db project into an MMDB file for faster lookups.

It's written in Go to allow it to compile to many platforms and run from a single binary.

Usage

The tool is designed to accept a correctly formatted CSV file input and convert it to an MMDB file output. It has several options:

Option	Short	Description	Compulsory?
-input	-i	The path to the input CSV file (relative or absolute)	Yes
-output	-o	The path to the output MMDB file (relative or absolute) If omitted, the input name will be used with the extension swapped	No
-type	-t	The type of record being converted: country, asn or city If omitted, the input name will be checked to see if it contains those words (or their plurals)	No
-ipv	N/A	The IP version that is being converted: 4 or 6 If omitted, the file name will be checked	No
-record_size	-r	The MMDB Record Size: 24, 28 or 32 If omitted, the file name will be checked and a sensible default chosen	No

ip-location-to-mmdb -i /path/to/input.csv -o /path/to/output.csv -t country -ipv 4 -r 24

Or if the files are named well (as named in the project):

ip-location-to-mmdb -i /path/to/dbip-country-ipv4.csv
