How to change where visitor come from

Hej ppl,

On my dashboard, in the “visitor here and now” log, i can see if a visitor come from google, or facebook, or and other page.

But if the visitor come from tracking.mywebpage.dk then it says: “Direct hit”, how can i do so it will display “tracking.myhomepage.dk

like if the visitor come from google or facebook etc.

Thanks for your help
