## Solution:

First of all, thanks to my teammate KOOLI, because he solved most of this challenge ?

...



We were given an ip address in the challenge description (**139.83.9.11**)



### To make a long story short, I will mention the solution directly:



My teammate found a geographic location when he checked the "**Historical Whois**":

(**38.129775 -6.976331**)

I checked the **Google Maps Street View** there, and I found the number:
