Using go install

Make sure that $GOPATH/bin is in your $PATH, because that's where this gets installed:

go install github.com/ipinfo/mmdbctl@latest

Using curl/wget

The pre-built binaries for all platforms are available on GitHub via artifacts in releases. You need to simply download, unpack and move them to your shell's binary search path.

The following OS & arch combinations are supported (if you use one not listed on here, please open an issue):

darwin_amd64
darwin_arm64
dragonfly_amd64
freebsd_386
freebsd_amd64

After choosing a platform PLAT from above, run:

# for Windows, use ".zip" instead of ".tar.gz"
curl -LO https://github.com/ipinfo/mmdbctl/releases/download/mmdbctl-1.4.6/mmdbctl_1.4.6_${PLAT}.tar.gz
# OR
wget https://github.com/ipinfo/mmdbctl/releases/download/mmdbctl-1.4.6/mmdbctl_1.4.6_${PLAT}.tar.gz
tar -xvf mmdbctl_1.4.6_${PLAT}.tar.gz
mv mmdbctl_1.4.6_${PLAT} /usr/local/bin/mmdbctl

Using git

Installing from source requires at least the Golang version specified in go.mod. You can install the Golang toolchain from the official site.

Once the correct Golang version is installed, simply clone the repository and install the binary:

git clone https://github.com/ipinfo/mmdbctl
cd mmdbctl
go install .
$GOPATH/bin/mmdbctl

You can add $GOPATH/bin to your $PATH to access mmdbctl directly from anywhere.

Alternatively, you can do the following to output the binary somewhere specific:

git clone https://github.com/ipinfo/mmdbctl
cd mmdbctl
go build -o <path> .

Replace <path> with the required location.

Quick Start

This will help you quickly get started with the mmdbctl CLI.

Default Help Message

By default, invoking the CLI shows a help message:

mmdbctl

Reading

You can read from MMDB files in various different ways - as individual IPs, CIDRs or IP ranges, coming from the command line as arguments, or from files, or from stdin.

Pretty JSON format:

$ mmdbctl read -f json-pretty 8.8.8.8 location.mmdb
{
  "city": "Mountain View",
  "country": "US",
  "geoname_id": "5375480",
  "latitude": "37.4056",
  "longitude": "-122.0775",
  "postalcode": "94043",
  "region": "California",
  "timezone": "America/Los_Angeles"
}

CSV format:

$ mmdbctl read -f csv 8.8.8.8 location.mmdb
ip,city,country,geoname_id,latitude,longitude,postalcode,region,timezone
8.8.8.8,Mountain View,US,5375480,37.4056,-122.0775,94043,California,America/Los_Angeles

TSV format:

$ mmdbctl read -f tsv 8.8.8.8 location.mmdb
ip	city	country	geoname_id	latitude	longitude	postalcode	region	timezone
8.8.8.8	Mountain View	US	5375480	37.4056	-122.0775	94043	California	America/Los_Angeles

Via a file:

$ cat ips.txt
8.8.8.8
8.8.8.0/31
8.8.8.0-8.8.8.1
8.8.8.0,8.8.8.1

$ mmdbctl read ips.txt location.mmdb | sort -u
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}

Via stdin:

$ echo 8.8.8.8 | mmdbctl read location.mmdb
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}

Multiple inputs are also possible - these all return the same thing:

$ echo -e '8.8.8.8\n1.2.3.4' | mmdbctl read location.mmdb
$ mmdbctl read 8.8.8.8 1.2.3.4 location.mmdb
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}
{"city":"Brisbane","country":"AU","geoname_id":"2174003","latitude":"-27.48203","longitude":"153.01358","postalcode":"4101","region":"Queensland","timezone":"Australia/Brisbane"}

Can check CIDRs and ranges - these will all return the same thing:

$ mmdbctl read 8.8.8.0/31 location.mmdb
$ mmdbctl read 8.8.8.0-8.8.8.1 location.mmdb
$ mmdbctl read 8.8.8.0,8.8.8.1 location.mmdb
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}
{"city":"Mountain View","country":"US","geoname_id":"5375480","latitude":"37.4056","longitude":"-122.0775","postalcode":"94043","region":"California","timezone":"America/Los_Angeles"}

Importing

Importing allows taking in files as CSV/TSV/JSON, and outputting an MMDB file.

Importing is one of the most powerful/flexible features in mmdbctl. However, we only allow strings throughout the data at the current time.

See mmdbctl import --help for full details on usage.

Here are some basic examples:

# basic CSV importing into MMDB.
$ mmdbctl import --in data.csv --out data.mmdb

# generate MMDB from a TSV file containing IPv4 data.
$ cat data.tsv | mmdbctl import --ip 4 --tsv --out data.mmdb

# don't include the implicit `network` field in the output MMDB:
$ mmdbctl import --no-network --in data.csv --out data.mmdb

# generate an MMDB without any fields, just IP ranges that meet a criteria.
$ mmdbctl import                                                              \
    --size 24 --no-fields --ip 4                                              \
    --in anycast.csv --out anycast.mmdb

Exporting

Exporting allows taking in an MMDB file and outputting CSV/TSV/JSON.

See mmdbctl export --help for full details on usage.

# basic export.
$ mmdbctl export data.mmdb data.csv

# basic export without a header.
$ mmdbctl export --no-header data.mmdb data.csv

# just see the number of entries it'd output.
$ mmdbctl export --no-header --format csv data.mmdb | wc -l

Metadata

You can retrieve data in the metadata section of the MMDB file using the metadata subcommand.

Pretty format:

$ mmdbctl metadata location.mmdb
- Binary Format 2.0
- Database Type ipinfo location.mmdb
- IP Version    4
- Record Size   32
- Node Count    123456789
- Description
    en ipinfo location.mmdb
- Languages     en
- Build Epoch   123456789

JSON format:

$ mmdbctl metadata -f json location.mmdb
{
    "binary_format": "2.0",
    "db_type": "ipinfo location.mmdb",
    "ip": 4,
    "record_size": 32,
    "node_count": 123456789,
    "description": {
        "en": "ipinfo location.mmdb"
    },
    "languages": [
        "en"
    ],
    "build_epoch": 123456789
}

Verification

You can verify if a MMDB file is correctly structured with the verify subcommand:

$ mmdbctl verify location.mmdb
valid

Let's force it to be invalid and check again:

$ cp location.mmdb location-tmp.mmdb
$ cat location.mmdb >> location-tmp.mmdb
$ mmdbctl verify location-tmp.mmdb
invalid: received decoding error (the MaxMind DB file's data section contains bad data (uint16 size of 11)) at offset of 13825601

Auto-Completion

Auto-completion is supported for at least the following shells:

bash
zsh
fish

NOTE: it may work for other shells as well because the implementation is in Golang and is not necessarily shell-specific.

Installation

Installing auto-completions is as simple as running one command (works for bash, zsh and fish shells):

mmdbctl completion install

If you want to customize the installation process (e.g. in case the auto-installation doesn't work as expected), you can request the actual completion script for each shell:

# get bash completion script
mmdbctl completion bash

# get zsh completion script
mmdbctl completion zsh

# get fish completion script
mmdbctl completion fish

Shell not listed?

If your shell is not listed here, you can open an issue.

Note that as long as the COMP_LINE environment variable is provided to the binary itself, it will output completion results. So if your shell provides a way to pass COMP_LINE on auto-completion attempts to a binary, then have your shell do that with the mmdbctl binary itself (or any of our binaries).

Color Output

Disabling Color Output

All our CLIs respect either the --nocolor flag or the NO_COLOR environment variable to disable color output.

Color on Windows

To enable color support for the Windows command prompt, run the following to enable Console Virtual Terminal Sequences.

REG ADD HKCU\CONSOLE /f /v VirtualTerminalLevel /t REG_DWORD /d 1

You can disable this by running the following:

REG DELETE HKCU\CONSOLE /f /v VirtualTerminalLevel
