has anyone else noticed or is it just me?

knoppix.com runs on iis6...

i didnt belive it at first but after some testing im 99% sure its running on iis6.


banner inspection seems to point that its iis6 as it gives the exact same response to a GET / HTTP/1.1 request with no hostname as microsoft.com does(ie hiding server).

Code:

but really what i want to know is why?

why is knoppix.com hosted on a windows box rather then a linux box?
