18.97.9.170

Multiple command line HTTP clients are supported, including curl, httpie, httpie-go, GNU Wget, fetch, and bat.

All endpoints (except /port) can return information about a custom IP address specified via ?ip= query parameter.

CLI examples

$ curl ipka.sk

$ http -b ipka.sk
18.97.9.170

$ ht -b ipka.sk
18.97.9.170

$ wget -qO- ipka.sk
18.97.9.170

$ fetch -qo- http://ipka.sk
18.97.9.170

$ bat -print=b ipka.sk/ip
18.97.9.170

Country lookup

$ http ipka.sk/country

JSON output

$ http ipka.sk/json
{
  "ip": "18.97.9.170",
  "ip_decimal": 308349354,
  "country": "United States",
  "country_iso": "US",
  "country_eu": false,
  "latitude": 37.751,
  "longitude": -97.822,
  "time_zone": "America/Chicago",
  "hostname": "18-97-9-170.crawl.commoncrawl.org",
  "user_agent": {

    "comment": "(https://commoncrawl.org/faq/)",
    "raw_value": "CCBot/2.0 (https://commoncrawl.org/faq/)"
  }
}

Setting the Accept: application/json header also works as expected.

FAQ

How do I force IPv4 or IPv6 lookup?

As of 2018-07-25 it's no longer possible to force protocol using the v4 and v6 subdomains. IPv4 or IPv6 still can be forced by passing the appropiate flag to your client, e.g curl -4 or curl -6.
