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.

Can I force getting JSON?

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