Just another "what is my IP address" service, including geolocation and headers information, written in go with high performance in mind, it uses [gin](https://github.com/gin-gonic/gin) which uses [httprouter](https://github.com/julienschmidt/httprouter) a lightweight high performance HTTP multiplexer.
|
|
|
|
Take a look at [ifconfig.es](https://ifconfig.es) a live site using `whatismyip`
|
|
|
|
Get your public IP easily from the command line:
|
|
|
|
```bash
|
|
curl ifconfig.es
|
|
127.0.0.1
|
|
|
|
curl -6 ifconfig.es
|
|
::1
|
|
```
|
|
|
|
## Features
|
|
|
|
- TLS and HTTP/2.
|
|
- Can run behind a proxy by trusting a custom header (usually `X-Real-IP`) to figure out the source IP address.
|
|
- IPv4 and IPv6.
|
|
- Geolocation info including ASN. This feature is possible thanks to [maxmind](https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?lang=en) GeoLite2 databases. In order to use these databases, a license key is needed. Please visit Maxmind site for further instructions and get a free license.
|
|
- High performance.
|
|
- Self-contained server what can reload GeoLite2 databases and/or SSL certificates without stop/start. The `hup` signal is honored.
|
|
- HTML templates for the landing page.
|
|
- Text plain and JSON output.

Golang >= 1.17 is required. Previous versions may work.
|
|
|
|
`make build`

## Usage
|
|
|
|
```text

## Examples
|
|
|
|
### Run a default TCP server
|
|
|
|
```bash
|
|
./whatismyip -geoip2-city ./test/GeoIP2-City-Test.mmdb -geoip2-asn ./test/GeoLite2-ASN-Test.mmdb
|
|
```
|
|
|
|
### Run a TLS (HTTP/2) server only
|
|
|
|
```bash
|
|
./whatismyip -geoip2-city ./test/GeoIP2-City-Test.mmdb -geoip2-asn ./test/GeoLite2-ASN-Test.mmdb -bind "" -tls-bind :8081 -tls-crt ./test/server.pem -tls-key ./test/server.key
|
|
```
|
|
|
|
### Run a default TCP server with a custom template and trust a custom header set by an upstream proxy
|
|
|
|
```bash
|
|
./whatismyip -geoip2-city ./test/GeoIP2-City-Test.mmdb -geoip2-asn ./test/GeoLite2-ASN-Test.mmdb -trusted-header X-Real-IP -template mytemplate.tmpl
|
|
```
