A self-hosted, non-tracking, and ad-free solution to reveal client-side IP info like IP address, conuntry, AS number/description, and additionally, user agent.

Demo

This project is also hosted publicly on https://ipinfo.tw, feel free to give it a try!

Please note that for privacy concerns, this demo is behind an reverse proxy with https enabled, which is not part of this project. http traffic will be redirected to use https to establish the connection, in case the plaintext data being snifferred/intercepted.

Usage

Server side

Run the server daemon via docker:

docker run -d --name ipinfo.tw -p 80:80 peterdavehello/ipinfo.tw:latest

If you want to put this container behind reverse proxy, set up an X-Real-IP header and pass the it to the container, so that it can use the header as the IP of the client.

Client side

Use any http(s) client to explore the server, e.g. https://ipinfo.tw,

• wget -qO- https://ipinfo.tw
• curl https://ipinfo.tw

Without any specified URI, the server will return IP address, country, AS, and user agent.

If you prefer to receive a machine-readable result, use path /json, e.g. https://ipinfo.tw/json, the result will look like:

{"ip":"3.115.123.234","country_code":"JP","country_name":"Japan","asn":"16509","as_desc":"Amazon.com, Inc.","user_agent":"curl/7.58.0"}

You can also specify the following URI to retrieve certain info:

• ip: IP address
• country: Country code and name
• country_code: Country code
• country_name: Country name
• as: AS number and description
• asn: AS number
• as_desc: AS description
• user_agent: User agent string

Examples:

$ wget -qO- https://ipinfo.tw
157.230.195.167
