Hi,

I am inside a company network. When I am browsing Internet, my internal IP is getting NATted and packets are sent outside. It is easy for web programmers to get my public IP through which it is NATted. But there are some websites which displays my public IP and even my internal IP. I went through the source code and cant find any code which tries to retrieve my internal IP. How exactly it is getting revealed???

Sorry I don't know the answer but we had something similar. Found a website that showed local directories of my c: drive to me.

(I think Activex was disabled, javascript and java were not)

Asked our network dept, one guy said it was a 'trick' but did not give me an answer.

Thanks Dij... I did a little bit study on this in some sites. What i came to know is there are events like '.getAddress()'in Javascripts n' VBScripts which will very well retrieve the IP address. These things can retrieve not only IP address but also details like Browser Information, Proxy Details and even integrating with Google map, they can display where exactly the user is located. The script is running on Server. Only the result will be displayed to the client. So that is the reason if we check the Source code of the page also we wont see any code to retrieve IP address.

Did you check your router, maybe you can silence your router for don't reveal that information or you hava an active x.
