Is DNS necessary???

Hi Guys,

I am presently networking three machines behind a Linksys router. They are all networking through the router. Each machine I have assigned an internal IP address and a DNS server. The DNS server numbers I found on the router UI through my browser. Where do I find a DNS server number for a fourth machine that I would like to introduce into the network? Will I be able to use the same IP and DNS numbers on each machine if two or three machines are hooked up to a Linksys hub, then from hub it goes onto the router?

Thanks in advance....

One unique IP for each machine, this is to identify them on the network.
The same DNS for all computers, this is the server used to look up other computers. Normally this can be the IP of your router, or an IP given by your ISP.

If your router has DHCP enabled and this is a temporairy computer, when the router assigns the IP it will also include the DNS IPs as well.

Yes. :) The reason you have three is that there are always at least one backup server (two in your case). You may have seen the lines "Primary DNS" and "Secondary DNS" in the settings? This is in case you want to type in two of the DNS servers in case the first goes down.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
