As the title suggests, I am curious if anyone has ever found a proxy/vpn that is not "known" as being a proxy or vpn. After trying every major proxy service, I am now convinced that there is no such thing. The first method of testing a proxy is to simply type the IP into a good proxy lookup service such as maxmind. It has never missed detecting a proxy or vpn and if they and others can detect proxies then there is no doubt that Google, Craigslist, or any other major website can detect proxies when trying to use their services. Also regarding Google, I have never seen a proxy/vpn "location" be accurate with what Google sees as the IP location. For instance, if you buy specific proxy IP locations and you use them with a Google account then you will always see a completely different location detected by Google than any IP location lookup tools will show you. In my experience this is because Google easily detects all proxies and shows the Datacenter as the "IP location" as opposed to what all other IP location tools will show as the IP location. As an example problem that I run into: If I need to create a Google/Gmail account in a specific location with a specific phone number in that location, it is not possible to do because as mentioned the proxy location that Google detects is never anywhere near the location that the proxy company claims the IP is from. In case you don't know, you can see what location Google detects for your IP by logging into any Google/Gmail account and going into the My Account -> Device Activity & Notifications -> REVIEW DEVICES, and then you will see the location that Google thinks your IP is from. So I suppose my long-winded question goes back to the title: Do Undetectable Proxy IP's Exist?
