    Just learnt Binary from a co-worker, all of these mythical numbers now make sense :)

    Will I need to know this for any of the MCSA/E exams?

    yep binary will help you loads in the 290 and 291 exams moreso the 291, did he teach you about subnetting and the x.x.x.x/xx notation as well.

    Doesn't the / command have something to do with the number of ones in the binary equivalent of the subnet.

    For example:

    255.255.0.0 consists of 16 ones and 16 zeros so that would be /16 which could then be added to an IP address.

    Following this threw it could be 192.168.0.0 /16 is that right? (might have for the IP range wrong, havent remembered all these yet)

    Yep, the number after a / in a written IP address is the number of ones in the subnet mask. So an address
    10.12.68.125/8 would have a subnet mask of
    255.0.0.0 (8 ones and 24 zeros)
    11111111.00000000.00000000.00000000

    172.16.55.55/16 would have a subnet mask of
    255.255.0.0 (16 ones and 16 zeros)
    11111111.11111111.00000000.00000000

    192.168.78.3/24 would have a subnet mask of
    255.255.255.0 (24 ones and 8 zeros)
    11111111.11111111.11111111.00000000

    I'm seriously pleased I have learnt this, as it used to baffle me when people mentioned converting binary to decimalisation.

    Now I understand it, it is actually pretty straight forward and hopefully will help out when I start hitting the server exams for the MCSA/E.

    What a strange coincidence...

    Just watching the CBT Nugget Network & Sharing Centre for the 70-620 and they are teaching IP addresses and Subnet Masks lol.

    Just learnt about Anding where you combine IP Address & Subnet Mask to determine if the destination is on the Local Subnet or if it goes to the Default Gateway.

    This networking stuff is starting to sink into place now :)

    I really like IP version 4. Its a really tidy and logical way of doing things. You will find yourself using the basics of IP quite often!
