## Features
|
||||
|
||||
- TLS and HTTP/2.
|
||||
- Experimental HTTP/3 support. HTTP/3 requires a TLS server running (`-tls-bind`), as HTTP/3 starts as a TLS connection that then gets upgraded to UDP. The UDP port is the same as the one used for the TLS server.
|
||||
- Beta DNS discovery: A best-effort approach to discovering the DNS server that is resolving the client's requests.
|
||||
- Can run behind a proxy by trusting a custom header (usually `X-Real-IP`) to figure out the source IP address. It also supports a custom header to resolve the client port, if the proxy can only add a header for the IP (for example a fixed header from CDNs) the client port is shown as unknown.
|
||||
- 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.
|
||||
- Checking TCP open ports.
|
||||
- High performance.
|
||||
- Self-contained server that can reload GeoLite2 databases and/or SSL certificates without stop/start. The `hup` signal is honored.
|
||||
- HTML templates for the landing page.

## DNS discovery
|
||||
|
||||
The DNS discovery works by forcing the client to make a request to `<uuid>.dns.ifconfig.es` this DNS request is handled by a microdns server
|
||||
included in the `whatismyip` binary. In order to run the discovery server, a configuration file in the following form has to be created:
|
||||
|
||||
```yaml
|
||||
---
|
||||
domain: dns.example.com
|
||||
redirect_port: ":8000"
|
||||
resource_records:
|
||||
- "1800 IN SOA xns.example.com. hostmaster.example.com. 1 10000 2400 604800 1800"
|
||||
- "3600 IN NS xns.example.com."
|
||||
ipv4:
|
||||
- "127.0.0.2"
|
||||
ipv6:
|
||||
- "aaa:aaa:aaa:aaaa::1"
|
||||
```
|
||||
|
||||
The DNS authority for example.com has delegated the subdomain zone `dns.example.com` to the server running the `whatismyip` service.
|
||||
|
||||
The client can request the URL `dns.example.com` by following the redirection `curl -L dns.example.com`.
|
||||
|
||||
To avoid the redirection, you can provide a valid URL, for example, for the real [ifconfig.es](https://ifconfig.es):
|
||||
|
||||
```bash
|
||||
curl $(uuidgen).dns.ifconfig.es
|
||||
|
||||
curl $(cat /proc/sys/kernel/random/uuid).dns.ifconfig.es
