7. Frequently Asked Questions

7.1. When will HTTPS be supported?

It pains me to say HTTPS will likely never be implemented. I know that throws a wrench in a bunch of implementations because they can never be HTTPS using an insecure API, but at this time a secure certificate is not available for the domain.

7.2. When will IPv4 be supported?

IPv4 will never be supported. The support of IPv4 is left up to the implementer. The tool was built with the future in mind and that future is IPv6. It is encouraged to handle IPv4 by converting it to the corresponding 6to4 network.

7.3. What IP is the empty query returning?

A request to the base URL without an IP address or tag query will replace the empty query with the client’s IPv6 address. If the client’s IP address is IPv4 it is converted to the corresponding 6to4 network by prefixing the IPv4 address with 2002::/16.
