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
