    I want to study DNS and DHCP. Do I need a router?

    Hi everyone. I am new to this forum and this is my first post.

    I have three laptops, three 2-meter straight-through cables, and a D-Link 8-port 10/100 Desktop switch (DES-1008A).
    I want to study DNS and DHCP in Ubuntu by creating a small INTERNAL network (1 server and 2 clients).
    I have installed Ubuntu 12.04 desktop i386 32bit in all three laptops and have downloaded and updated all necessary files for my study.

    My questions are:

    1. Do I need to buy a router? If so, what is the exact model of the cheapest router that will suffice for my needs?

    2. If I don't need a physical router, how will I configure my default gateway?

    Thanks in advance!

    If the server allows you to install a second network card, you can configure it to be a NAT router.

    Alternatively you can just buy a basic router for $25-30 from some place like NewEgg. Read the reviews.
    If you ask for help, please have the courtesy to check for responses and thank the people who helped you.

    I have a separate Ubuntu box set up as DHCP/DNS server. I disabled the DNS/DHCP server in my router.
    ( I also bought a used DLink WRT-54GL with Tomato ... although I haven't put it online, yet.)

    My first router was a floppy-based Freesco dial-up machine.
