# geoip-api

HTTP API for converting an IPv4 address to a country code.

Uses the [`iptoasn.com`](https://iptoasn.com) dataset.

## Setup

Grab the latest `ip2asn-v4.tsv.gz` and extract it to `data/ip2asn-v4.tsv`.

Then just use `cargo` as usual.

## Usage

```shell
$ http GET 'http://127.0.0.1:8000/192.168.0.1'
```

```json
{
  "asn": 0,
  "country_code": "None",
  "asn_desc": "Not routed"
}
```
