DNS

Hello guys! I want to ask you a few questions about DNS: 1) if my router is from my ISP and it needs PPoE access (username and password) does that mean that I can't change DNS? Are these two thing connected or not? I've no option to change the DNS in my router 2) if a certain device like a pc or phone has set a manual DNS like opendns one but the router has its own DNS, does my ISP still get the logs?

The DNS your computer is using is always specified and controlled by your computer. You can configure any computer to use any DNS you want, and in theory no other DNS should be used other than what you specify. You'll have to disable DHCP configuration on the computer to do this.

Your ISP will always be able to log which sites you visit (although not necessarily what you're doing on them, if the connection is secured with HTTPS/TLS, etc.), unless you're using an encrypted tunnel of some kind such as Tor, I2P or a VPN.

If you are concerned about privacy you might consider OpenNIC instead of OpenDNS, they have a list of DNS servers of which many aren't logged.

Protocols sit on top of each other and PPPoE is at a lower layer than DNS. Imagine you have a buzzer and a button at each end of a pair of cables and are sending messages using Morse Code. The buzzers and buttons are your phone hardware, the electricity running over it is the phone network, the way that long and short beeps relate to letters of the alphabet would be something like PPPoE, the English language would be Internet protocols and the cake recipe you're discussing would be HTTP.

Anyway, as part of the internet protocol suite there's a thing that dynamically assigns you an IP address, tells you the IP address of the gateway to the Internet, and the IP addresses of your DNS servers. You can disable it or override the DNS servers if you like.

2) if a certain device like a pc or phone has set a manual DNS like opendns one but the router has its own DNS, does my ISP still get the logs?

DNS is not encrypted so it's possible that your ISP are logging the requests even if you aren't sending requests to their servers. It's unlikely though because that would cost money and have no real business value. NSA are certainly logging them though. Your router can't override manually set DNS settings though, at least it's unlikely that it can.

DNS has nothing to do with logging with the ISP... you know when you fat-finger it and type google.cm or something that little search engine pops up and says did you mean google? thats a feature of DNS. it also is the white pages of the internet and why typing google.com = 173.194.46.46 in your router will be a dhcp type section and there you can manually set up a DNS otherwise yes setting it on the computers will effectively do the same
