Which DNS server?

Hey guyz, i have never thought such thing. Lets say, i have a computer which's DNS server set as 8.8.8.8 and 8.8.4.4. However,
it is set as 195.56.34.1 and 195.56.34.2 on the broadband modem.

When i wanna display web page, which one will be used to resolve? and why?

It will use 8.8.8.8 and 8.8.4.4 because it knows nothing of the broadband modem's settings.

Yes, like what you said. Though, whats the difference between them ? What happens if i want to use modem's DNS?

195.56.34.1 and 195.56.34.2 are DNS servers that belong to the ISP

8.8.8.8 8.8.4.4 belong to Google

if you want to use the modems ones jsut point the PC dns settings to the modems address, which will be some thing like

192.168.0.1

the computer will then send requests to the modem that will in turn forward them to the 195 address.

at the moment the pc communicates directly with 8.8.8.8 and 8.8.4.4

You could also hard code the modem address directly in to the PC in which case it would bypass the modem altogether.

If you want to use your modem's DNS then program it on your home router, easy.

Also, the difference between 8.8.x.x are google's and the others are from your ISP provider.

If I were you, I'd stick with the 8.8.x.x domains, since they're always running - i've always had no end of issues when keeping my DNS set on the local ISP.

I do agree with the last statement I have always used internet public DNS servers. now I use google 8.8.8.8 8.8.4.4 but have also used open DNS servers a lot in the past.

Although I would suggest you set you modem to use the Google servers, and then point your PC's to you modem. This means if for any reason the google servers fail, or you want to change to a different service, you only have to up date your modem settings.

Also (and for a home nwetwork this is not a real issue) your modem will/may cache address it resolved, meaning that if you have mutiply PC requestion the same name, only one request will be sent to the internet server and the modem will remember the address and resolve further requests from other PC's faster and with out having to send data across the internet. As I say for a home network there is little benefit, but if you have a network with 100/1000's of pc's having a DNS relay server onsite, can show noticeable gains in time taken to resolve addresses and bandwidth usage.

Whatever your local host has configured for DNS servers is where the query will go.

Assuming your providers network doesn't kill it, or doesn't hijack it and redirect to their own DNS servers, then that's also where your query will run.

I'd be careful about using the Auto/DNS from your ISP provider option as it may put you on a DNS server that is waaaaaaaaaaaaay far away from where you are. My ISP has DNS servers here and that's what I'm supposed to be using. My router, when it automatically queries my ISP for it's DNS server address, hooks me into a DNS server that my ISP runs in the mid-west and it doesn't always work well. I didn't even know it was happening until I closely poked around my router settings and ran the DNS server's IP address it had gotten from my ISP.

Hmm interesting tool Robert, thanks for the link!
Might try this out at home

Keep in mind that for the results to be meaningful you should run multiple tests during the time of day you will actually be using the servers. Certainly time of day has a bearing on average load.

Sorry guyz, i couldn't visit the forum for a while. though, i have checked every posts here

As far as i realise

the priority is on my local interface's DNS server settings according to what you told me, then modem's come. Right?
