Usage

Server side

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

• 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
