GoGeoIP

A fully self-hosted Rest IP to fetch Geo information for an IP. Geo information such as City, Country, ASN, Organization etc., details.

Rest API depends on MaxMind City, Country & ASN Lite database.

MaxMind offers City, Country & ASN Lite databases for free for individual uses.

The program downloads City, Country and ASN databases from MaxMind and runs lookups on local DB.

Features

Rest API to translate IP to Geo info
Automatically download, verify and load MaxMind lite databases on boot.
Regularly run jobs to update MaxMind local databases.
No API lookup limits.

Getting Started

GoGeoIP is packaged as docker container. Docker image is available on Docker Hub.

To use GoGeoIP, you require MaxMind license key to download lite databases. Head over to MaxMind and sign-up for a free account.

Get MaxMind License Key

Login to MaxMind
Click on Manage License Keys in left side menu.
Click on Generate new license key, fill out description and click confirm.
Save license key safely

Docker run

docker run -it -p 5000:5000 -e DB_LICENSE_KEY=<LICENSE_KEY> -e API_LISTEN_ADDR=0.0.0.0 -e API_KEYS=test-key hibare/go-geo-ip

Replace <LICENSE_KEY> with the license key from MaxMind. Replace test-key with randomly generated API key. This is used to authenticate all IP lookup rest calls.
