whatsmyip.com shows my internal IP behind NAT ?? How to block it ?
« on: July 13, 2018, 11:42:05 pm »

I opened the whatsmyip.com website, which showed my public IP.  No surprise there.

However, it also showed the inside IP address of my laptop ?

Is there any way to block this information ? I just want my outside IP to show, not which internal machine is behind the session ?!

Do you use a proxy (or transparent)?

That's neat. I don't use a proxy at all and I can my LAN address there too.

Same for my, i dont use a proxy either..    it not such a big issue that a private ip shows up, it's not routable from the outside.. but it does identify th eip of the specific computer, which is a privacy issue..

After reading the article mentioned above it seems that my chrome browser is leaking this info..


Very strange..  stopping this would mean pluging every browser of every client pc..    hmpff
