I just don’t get the difference between the two because they both seem similar to me.
Oh, OK, that’s a pretty good analogy, thank you!
Oh, and if I’m correct, I want to use a Private DNS to stop my ISP from checking me out, correct?
Most vpn providers offer you the use of their own DNS servers (instead of your ISP’s) so you are in effect ‘hiding’ that as well as your data stream from your ISP. To be clear though, even with VPN you are not hiding anything upstream of the VPN provider’s endpoint servers; it still goes out on the internet from there onward.
What DNS provider do you use on Android? If you use an android.
How do I hide the dialing numbers from ISP?
