    Learn to Subnet is a pretty good free site that I found useful when studying for my Network+.

    It seems to work best in Internet Explorer. You may find some of the early lessons cover the same materiel a few times, but it's worth sticking it out.

    I went for option 3 (Platinum Pack) which works out around £13.57... like i said its very useful... if you keep at it you'll learn it in no time. :)

    CSX is absolutely right.

    The full package should cost a lot more IMO. Because by time you watched the video, you WILL know how to subnet. By the end of the week you'll be subnetting like an old pro.

    Trust me on this.

    mbr2,

    Since I have recently recertified as a CCNA and personally used this method when I was taking the 640-801 CCNA exam, it may help you.

    First, let the encapsulation process from the Application Layer down to the Physical Layer help you with the subnetting process. For example, do you know if the routing protocol will be either RIP v1 or IGRP? If so, then the subnet mask is going to be either 255.0.0.0, 255.255.0.0, or 255.255.255.0 because those routing procotols support only classful subnet masks.

    Second, the subnetting process itself. For me, there are at least 6 questions:
    1. What is the class of the IP address?
    2. What is the default mask for the IP address?
    3. What is the subnetwork number?
    4. What is the first valid IP address?
    5. What is the last valid IP address?
    6. What is the broadcast IP address?

    I hope this helps.
