The HOSTIP.INFO database would not be here if it weren't for the contributions of many. Below is a list of people who have given their contributions to build a better and more accessible database for your use. This is a very active project, and if you are interested in contributing, email me at contrib@hostip.info for more information.

Many thanks to:

• Simon Gornall - founder of the hostip project and database, and also built most of the API functions in use today!
• Ozone - added flags for private networks.
• Ries van Twisk - ported install scripts, etc to PostgreSQL
• Makamaka Hannyaharamitu - Hostip.info perl module for easy retrieval of addresses (you can get this in CPAN at WWW::HostipInfo)

API Extensions:

• Mateusz Banach - wrote a python front-end to the hostip interface
• Daniel K.O. - has written an OpenGL replacement for the net-in-a-box SDL one that Simon hacked together. It's mirrored here.
• Carlos Averett - has written a PHP function to locally-cache results from the server. This allows you to have a halfway-house between the full-on slave server, and the hit-hostip.info-all-the-time model. Excellent :-)
• Hutch Ingold - wrote a nice script to plot visitor 'hits' on a map (using php and png graphics). You can find it here Map IP Addresses of Visitors.
• Matt Briney (w/Steve Jones patch) - wrote a nice little ASP script to parse Geolocation information
• Tim Hibbard - wrote a quick .NET version of the Hostip API
• Kiichi Takeuchi - wrote a C#.NET version of the Hostip API (inspired by Tim Hibbard's .NET version)
• Carlos Averett - phpAdsNew geotargeting phpAdsNew plugin for geotargeting
• Chris McKeever - Quick and dirty API parser for PHP hostip-parse.php
• Marcus K - Quick way to rsync and keep up-to-date with Cygwin
• Oscar de Lathouder - Access the api.hostip.info interface to hostip.info using flash
• Andrew Turner - Nice module to interface with api.hostip.info in ruby
• Whereis IRC Bot - Bot allows you to ".whereis [nick]" and return a location
• Hans Oesterholt-Dijkema - PLT Scheme Module for geolocation of ip numbers and hosts
• David Roberts - wrote a nice bash script that updates hostip

Mashups / Plugins:

• Robert Accettura - Plots websites based on their coords GeolocateFox Firefox Plugin
• Michael Bekaert - small php script based on GeoCounter idea able to visualize IP Addresses and website hits with Google Earth
• Sergey Kirienko - small Firefox plugin that shows country flag, country name, and city name of website on status bar Geoloc Firefox Plugin
• Claudio Fleiner - Google maps traceroute and visitor maps
• Andrew Hedges - IP Locator Dashboard Widget

There is a public Git repository available for all interested developers (and people wishing to see how this works). Please feel free to make any patches necessary - and also add anything if you feel inclined (this project was built by some excellent contributors, so don't hold back!) If you become a frequent contributor I'll give you committer access to the repo, and you can commit by yourself. To get started though, do a pull and if you make something send the patches to source@hostip.info (or new features, etc…)

Hostip.info takes not only time, but plenty of bandwidth and other resources (hosting, etc). If you would like to make a donation, no matter how large nor small, we always appreciate it! There are many pay-for-geo-ip services out there, but we truly believe a community effort really works best. Help us keep this service free. Thank you!
