I don't understand to what extent using a VPN masks your IP address.
My questions arise from two observations.
1. I normally use w3m as a browser with no user-agent setting. Frequently
if I issue several google requests using inurl:something
google will take me for a robot and shut me down. I have tried using
openvpn and a public vpn and repeating the request but google still
recognizes me and refuses my request.
2. Some of the BBC sites allow access only from within the UK. As
a test of a commercial VPN I make connection to a VPN server
in Manchester, UK from my actual site in Southern California.
The BBC recognized that my request was coming from outside the
UK and denied access.
I have tried the webrtc test from github with the Chrome browser and
with javascript enabled I see only a local IP address from the
VPN, and neither the VPN or my address. I see nothing from Chrome
when javascript is disabled.
In all cases What is my IP shows the VPN server address as I would
expect.
How does google or the BBC determine my real IP address?
Thanks.
