NAME

mmdblookup - a utility to look up an IP address in a MaxMind DB file

SYNOPSIS

mmdblookup --file [FILE PATH] --ip [IP ADDRESS] [DATA PATH]

DESCRIPTION

mmdblookup looks up an IP address in the specified MaxMind DB file. The record for the IP address is displayed in a JSON-like structure with type annotations.

If an IP's data entry resolves to a map or array, you can provide a lookup path to only show part of that data.

For example, given a JSON structure like this:

{
    "names": {
        "en": "Germany",
        "de": "Deutschland"
    },
    "cities": [ "Berlin", "Frankfurt" ]
}

You could look up just the English name by calling mmdblookup with a lookup path of:

mmdblookup --file ... --ip ... names en

Or you could look up the second city in the list with:

mmdblookup --file ... --ip ... cities 1

Array numbering begins with zero (0).

If you do not provide a path to lookup, all of the information for a given IP will be shown.

OPTIONS

This application accepts the following options:

-f, --file: The path to the MMDB file. Required.
