All the next are only my assumptions. There are simplified and abstruct models. I want to know what is the way of my packeges when I use the ISP DNS and OpenDNS. And what is the way when I use VPN and I have the DNS leak (my ISP DNS) and the second way when I use VPN without DNS leak (OpenDNS)? I am connecting to the google.com in the all 4 cases.

  1. I just use ISP DNS:

My computer (tries to connect to the google.com) ---> my ISP router (searches google IP) ---> my ISP DNS (returns google IP) ---> my ISP router (tries to connect to google.com) ---> ... ---> server ISP router ---> server

and back

server ---> server ISP router ---> server ISP DNS ---> server ISP router ---> ... ---> my ISP router (gets the data from google.com) ---> my computer (gets the data)

In this case, the google.com IP is known by ISP DNS and by my ISP and my IP is known by server ISP, server ISP DNS and server.

  1. When I use OpenDNS:

My computer (tries to connect to the google.com) ---> my ISP router ---> OpenDNS (returns google IP) ---> my ISP router (tries to connect to google.com) ---> ... ---> server ISP router ---> server

and back

the same as the case 1.

In this case, the google.com IP is known by OpenDNS and by my ISP and my IP is known by sever ISP, server ISP DNS and by the server.

  1. When I use VPN and my ISP DNS:

My computer (tries to connect to the google.com and encrypts the data) ---> my ISP router (searches google IP) ---> my ISP DNS (returns google IP) ---> my ISP router (tries to connect to VPN) ---> VPN ---> ... ---> server ISP router ---> server

and back

server ---> server ISP router ---> server ISP DNS ---> server ISP router ---> ... ---> VPN ---> my ISP router (gets the encrypted data from VPN) ---> my computer (gets the data)

In this case, the google.com IP is known by my ISP DNS, my ISP and my VPN, my IP is known by my VPN.

  1. When I use VPN and my OpenDNS:

My computer (tries to connect to the google.com and encrypts the data) ---> my ISP router ---> OpenDNS (returns google IP) ---> my ISP router (tries to connect to VPN) ---> VPN ---> ... ---> server ISP router ---> server

and back

the same as the case 3.

In this case, the google.com IP is known by OpenDns and VPN, my IP is known by VPN.

If this models are not correct, please show me the correct. I cannot find the explanation.

Please, use the same "diagrams" as I have used.
