Short Description
Free geoip to run on brandfolder.
Full Description


This is the source code of the freegeoip software. It contains both
the web server that empowers, and a package for the
Go programming language that enables any web server
to support IP geolocation with a simple and clean API.

See for details about geolocation.

Developers looking for the Go API can skip to the Package freegeoip
section below.


This section is for people who desire to run the freegeoip web server
on their own infrastructure. The easiest and most generic way of doing
this is by using Docker.

See the Server Options below for more information on configuring
the server.


Install Docker on Ubuntu 14.04 LTS:

sudo apt-get install

Install Docker on CentOS 7:

yum install docker

Run the freegeoip web server:

docker run --net=host --restart=always -d fiorix/freegeoip


curl localhost:8080/json/

See the API section below for details.

Other Linux, OS X, or FreeBSD

There are pre-compiled binaries available. You'll have to set up your own init scripts for your system.

There is also a Chef cookbook to deploy it automatically.

Server Options

You can configure the freegeoip web server to listen on a port
other than the default 8080, and also listen on HTTPS by passing
an ip:port and X.509 certificate and key files.

These and many other options are described in the help. If you're
using Docker, you can see them like this:

docker run --rm -it fiorix/freegeoip --help

By default, the Docker image of freegeoip does not provide the
web page from, it only provides the API.

If you want to serve that page, you can pass the -public=/var/www
parameter in the command line. You can also tell Docker to mount that
directory as a volume on the host machine and have it serve your own
page, using Docker's -v parameter.

If the freegeoip web server is running behind a proxy or load
balancer, you have to run it passing the -use-x-forwarded-for
parameter and provide the X-Forwarded-For HTTP header so the web
server is capable of using the source IP address of the connection
to perform geolocation lookups when an IP is not provided to
the API, e.g. /json/ vs /json/


The current implementation uses the free GeoLite2
database from MaxMind.

In the past we had databases from other providers, and at some point
even our own database comprised of different sources. This means it
might change in the future.

If you have purchased the commercial database from MaxMind, you can
point the freegeoip web server or Go API to the URL of it, or local
file, and the server will use it.

In case of files on disk, you can replace with a new version and the
freegeoip software will load it automatically. URLs are frequently
checked in background, and if a new version of the database is
available it is loaded automatically also.


The freegeoip API is served by endpoints that encode the response
in different formats.



Returns the geolocation information of your own IP address, the source
IP address of the connection.

You can pass a different IP or hostname:


To lookup the geolocation of after resolving its IP address,
which might be IPv4 or IPv6.

Responses can also be encoded as JSONP, by adding the callback parameter:


Same semantics are available for the /xml/{ip} and /csv/{ip} endpoints
except the callback parameter.

Metrics and profiling

The freegeoip web server can provide metrics about its usage, and also
supports runtime profiling.

Both are disabled by default, but can be enabled by passing the
-internal-server=:8081 parameter in the command line. Metrics are
generated for Prometheus and can be queried
at /metrics even with curl.

HTTP pprof is available at /debug/pprof and the examples from
the pprof package work.

Package freegeoip

The freegeoip package for the Go programming language provides two APIs:

  • A database API that requires zero maintenance of the IP database;
  • A geolocation http.Handler that can be used/served by any http server.

tl;dr if all you want is code then see the example_test.go file.

Otherwise check out the godoc reference.


  • Zero maintenance

The DB object alone can download an IP database file from the internet and
service lookups to your program right away. It will auto-update the file in
background and always magically work.

  • DevOps friendly

If you do care about the database and have the commercial version of the
MaxMind database, you can update the database file with your program running
and the DB object will load it in background. You can focus on your stuff.

  • Extensible

Besides the database part, the package provides an http.Handler object
that you can add to your HTTP server to service IP geolocation lookups with
the same simplistic API of There's also an interface for
crafting your own HTTP responses encoded in any format.


Download the package:

go get -d

Install the web server:

go install

Test coverage is quite good and tests may help you find the stuff you need.
