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/CORSto 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
IPv4 Only
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.
