    How to choose a DNS server for a network?

    Hi everyone,

    When we setup a network, we can assign the IP for each computer manually if we want. The IP assigning to each computer has to be in the range of the rounter IP, right? For example, if the default rounter IP is 192.168.2.1 then we can assign the first computer with an IP 192.168.2.2, the second one is 192.168.2.3, etc. But how do we choose the DNS server? what do we base on in order to choose a DNS server?

    Thank you so much for any help.

    Use the DNS servers provided by your ISP. The router itself is probably acting as a DNS cache itself, but those things can be flaky so it's best to set your PCs to go straight back to the ISP's servers.
    Safe computing is a habit, not a toolkit.

    Thank you Tuttle. I use Rogers cable, but they don't provide any DNS. How do I check it out?

    You should be able to just ring them and ask what their DNS servers are. However, given what I know about US broadband ISPs, it may not be that simple.

    [Side rant: Hey, US ISPs! How about something like this, or this, or this? It's not that hard...]

    If that fails, you might be able to log into your router's web interface and see what DNS server addresses it's been assigned by Rogers. If it tells you, then use those.

    Other than that, you have two options. One is to use 24.153.23.66 and 24.153.22.195 (which work now, but could potentially be moved around by Rogers at whim) or to just set your PCs to 192.168.2.1 and rely on the router's DNS cache.

    Don't forget to set the default gateway on each computer, too. Without it, the computers won't know how to access other networks than the local network. The gateway IP is the router's IP on the internal network, usually 192.168.1.1 .
