Location and IP Addresses

I’ve played a bit in Glide & AppInventor with using IP Address to find location .

I was reading Jack Dunnings blog about getting IP Address and putting it onto a map, with his IPFind.ahk script and decided to look mine up on this website What Is My IPAddress and this is what it returned:

So its giving location of my broadband provider rather than my specific IP Address. The interesting thing is its got the IPv6 as well as the IPv4 address. So only specific to Wellington city, no further granularity.
