ipify - A Simple Public IP Address API

I came across ipify - A Simple Public IP Address API when I was looking at a way to hide my research links from the normal visitor but have them visible to me.

Some time back I was convinced that if I had outbound links on my pages it would effect my page-ranking. Things have moved on and not only don't I care but I think that search engines such a Google have also moved on. The major problem with outbound links is that visitors having found the link that they were looking for they just move on.

The call to the ipify API returns the string above.
