Ever needed the user's IP but didn't want to write backend-scripts or didn't have access to it, because a reverse proxy returned a wrong address? (Well, look at that, I've just got the "perfect" solution for you.)
We now offer our IP-Service ip.timedin.net.
You can get the preferred address by the client (ip.timedin.net), only the IPV4 (ip4.timedin.net) or only the IPV6 (ip6.timedin.net). Also, it's possible to get both addresses with just one request (technically there are still two request, but you only need to send a request to one URL), using the Keyword (ip.timedin.net?both).
