network question


Hi there,
I am trying to setup a network for sharing an intranet.
I was just curious to know the principles of IP (in short).

My Redhat linux has 3 IP addresses:
1) IP adress from the internet provider (using adsl usb modem)
2) networkcard IP 192.168.1.1
3) localhost 127.0.0.1

Because I was thaugh that computers can only identify themself with one unique IP address, I was wondering if comflicts could accur e.g. giving a computer a network IP adres which is the same as an internet adres somewhere.

...your adsl IP is the 'unique' to the internet...it can be 'seen' from another machine on the net

the network card IP is for your LAN

that localhost is just a loopback...if you have a http server running (apache..) typing 127.0.0.1 in the server's browser will let you view what your server holds (webpages...) typing 127.0.0.1 from another computer however will not show the same results..

so basically you set up a machine with that adsl modem as a gateway/router/firewall...whatever and run all your computers through this...your local network addresses can be whatever you want
