# Meta
*Meta* is a small Nginx/PHP tool displaying some informations in order to debug or satisfy your curiosity.
## Use
### Paths
`/me` will redirect to `/<your-ip-address>`
`/<any-ip-address>` will print informations obtained from databases located in the `geolite2` directory
`/emoji` will print an emoji list
`/<anything-else>` will print *IP*, *TCP*, *TLS* and *HTTP* metadata
### Domains
`meta.4.niv.re` have working A (IPv4) and AAAA (IPv6) records
You can test IP version connectivity by forcing it throught
* `ipv4.meta.4.niv.re` only have the A record
* `ipv6.meta.4.niv.re` only have the AAAA record
### Ports
You can try to connect to a few other TCP ports than 443, using IPv6.
## Installation
### Nginx configuration
```
