    Use a class C private IP address range starting from 192.168.0.1 onward. In your case the printer doesn't need an IP, but the PC (the print server) which connects to it, does.
    question: If I use private ip addresses in both my computers, then what will happen when I connect to the internet using dial-up? After establishing the connection, won't my machine get another ip address from the ISP?

    if your isp does reassign ip addresses and it messes up your network (I really don't know if it will or not). Just use MAC addresses to connect everything.

    a dial up adapter won't assign the IP of your network card. They are two separate IPs. One external, one internal.

    As I understand it, private IPs are not assigned to computers which are connected to the net, and they're wholly for internal use. Every node on your n/work needs to probably use NAT/IP masquerade to reach the outside world that is thru your ICS.

    Hmm..not an expert at all here

    BTW, Waldo2k

    How does one go abt to:

    Just use MAC addresses to connect everything.
    There needs some special configuring?

    well, in case you didn't know, MAC addresses are hardcoded into the NIC's. Routers use a relational database that correspond IP's to MAC addresses, we use IP addr's becuase trying to use a single MAC address to locate a computer on the net is nearly impossible...but it works quite well in small networks. I've never actually set up using MAC addresses myself, I don't know if windows supports it internally or not, you may have to use 3rd party proxy software to use MAC addresses...but as I see it you don't need to use them.

    I agree these are two types of ip addresses. But A host can have only one ip address. As far as I know when a connection is established with dial-ups, the isp dynamically assigns an ip address for the host and thats how the host can communicate with the outer world (internet). This is what makes me confused. If I already assign an ip address (private) to my machine, how will it react when the isp tries to allocate an ip address to this machine when it is connected?

    P.S. The same problem remains (well as far I understand!) if I use NAT or CIDR. Because how will I configure the router if I don't know what ip address I will be assigned dynamycally by the isp?

    Ask for a fixed IP from your ISP then. They should be able to help.

    I don't know of a single ISP that provides static IP address to dail up users.

    Of course with enough money it should be plasible.

    No. Each interface usually has an IP address. That means if you have a machine with 3 network cards and a dialup connection you will typically have 4 ip addresses.

    Give it a try.

    While on this subject what is the easiest way to share a ethernet cable connection on my desktop and a laptop I'm going to get. My desktop will be running Windows and I'm installing Mandrake on the laptop if that will affect anything.

    won't affect a thing (as long as you can decide which one will be the server, which will be the client) setting up networks is mostly IP addresses, doesn't have anything to do with OS's.

    Ok. So Do I just need to connect them together with a networking device and what thing do I need to install on my desktop which will hold all the networking stuff to make it work?

    Why bother about server or client? Isn't it the easiest to use peer to peer in this case?
