API Help

• Accessing this info on the api
  https://jsonip.com/about
• Direct requests
  Visit in a browser or make requests to jsonip.com directly.
• CORS (Cross Origin Resource Sharing)
  To execute CORS requests, the originating request must be sent with the Origin header.
  The api will respond with the "Access-Control-Allow-Origin: *" header.
  Visit https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS to understand how it works.
  The JavaScript Fetch api will do this when "mode: cors" is enabled.

  fetch('https://jsonip.com', { mode: 'cors' }) .then((resp) => resp.json()) .then((ip) => { console.log(ip); });
• JSONP
  To use JSONP, set your callback function as https://jsonip.com/myfunc or https://jsonip.com/?callback=myfunc.

  myfunc({\"ip\":\"123.456.789.012\"})
• IPv4 Only
  To only get an IPv4 address, make requests to https://ipv4.jsonip.com.
  If the client only has an IPv4 address, they will be unable to connect to https://ipv6.jsonip.com.
• IPv6 Only
  To only get an IPv6 address, make requests to https://ipv6.jsonip.com.
  Most clients that are assigned IPv6 addresses have a fallback IPv4 address.
  However, if the client only has an IPv4 address, they will be unable to connect to https://ipv6.jsonip.com.
• HTTP Only (No SSL/TLS)
  By default all requests to jsonip.com are secured via https. For example, a request to http://jsonip.com returns a 301 redirect to https://jsonip.com.
  If you need to access the api via http (non-secure), use http://no-tls.jsonip.com.
