- 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.
