Maybe this does not belong in a Rogers forum and if so, let me know and I accept that.
There are three places I know of to enter DNS servers in my setup:
- Rogers modem - Hilton CGN3
- My router - ASUS RT-N66U
- In my Operating System (OS) network settings - I use Linux Mint but Windows would be the same I assume.
If CGN3 is not bridged (is in gateway mode) with no router ... easy ... the DNS servers in there are used.
If I bridge CGN3 and set my ASUS router to control DNS settings to some OpenNIC DNS servers ... I assume (hope) they would be used. I can not tell as my OS reports only one DNS server ... 192.168.1.1 (very bottom of code below) ... I know that is not really what they are but I have no idea what is used for sure.
IPv4 Settings:
Address: 192.168.1.189
Prefix: 24 (255.255.255.0)
Gateway: 192.168.1.1
DNS: 192.168.1.1
If I leave the ASUS router above 'as is' with my custom DNS servers in there .... BUT if I enter the same DNS servers into my OS network settings ... and run the same tool to ask what are my DNS servers ... its reports them as what I entered as seen below:
IPv4 Settings:
Address: 192.168.1.189
Prefix: 24 (255.255.255.0)
Gateway: 192.168.1.1
DNS: 198.xxx.xxx.xxx
DNS: 208.xxx.xxx.xxx
This is confusing to me as I don't know what really has priority to control my DNS servers. I will guess that my ASUS router would trump the Rogers modem ... and then my OS would trump both of those? Can anyone tell me. Kinda like ... the closer to home is the BOSS?
I got onto this because when trying to find fastest DNS servers using namebench or the one from GRC (Steve Gibson I think), they would not test my DNS servers in my router as tthey were reported as 192.168.1.1
