Provocative question, but in any case, this is what it would appear... unless there's some other reason, of course.
In my cystat wordpress log, I obtained the following entry
IP Browser OS Date Method Type URL
127.0.0.1 Safari 419.3 iPhone July 30, 2009 7:39 pm GET BLOG /blog/
The IP address is the IP of the visiting client. It's clear that this is not possible. Why do I get 127.0.0.1 as IP? cystat bug? some weird network trick I am not aware of? or is my website really running on an iPhone, and the guy at the applestore is reading my blog ?
