    spending whole semester dealing with a fine strategy to solve subnetting questions ,and here we go 9 minutes of explanation and all my doubts solved .that's magic of correct teaching method.

    Sir you are truly gifted. I have direct this video to many people and it was like the heavens opened up. I did have to watch a few times to get the rhythm, but it was worth it. I now understand how to do a subnet. Thank you so much.

    Having been a graduate of Cisco Acadamy in 1998, this is a great refresher. I just wish I did not have a unknown sickness from making me study harder and obtain my ccna. My first job would have made me make well over 70,000 the first year. I install routers and switches all day long just that the remote cisco engineer does the software and want to break away from Nationals and have my own customers.

  • @mybluemars
    @mybluemars 13 років тому +3

    I like your videos a lot! I just want to point something else out: Unless I'm wrong, you should have 3 subnets there because the connection between routers is also a network! It is a little confusing the way it is presented. Having said that, TY for uploading, and I appreciate the hard work you put into these! Matt

    Failed CCNA exam twice thinking I had it both times. I'm not sure if I want to go for a third. That thing is pure, ego-destroying evil . Feels like I've been assaulted in a dark alley by a gang of 1's and 0's, all of which were of course, wearing /masks. You win Cisco.

  • @danscourses
    @danscourses  13 років тому

    @relisys001 Yes, if the netmask is 255.255.255.0 then they are both on the same subnet or network, 192.168.1.0 /24. To make to subnets 192.168.1.0 and 192.168.1.128 you would need netmasks of 255.255.255.128

  • @lincolnchibvongodze8440
    @lincolnchibvongodze8440 8 років тому +28

    Truly speaking ........have you noticed that on the right side the IP Addresses are in 192.1.1.0 network.......and the left side is 192.168.1.0 network..........the concept is fine but I can argue with that because he said it can't be in the same subnet .......

    • @baaboo05
      @baaboo05 6 років тому +3

      Correct! This would only work if all of the segments were on the 192.1.1.0 subnet with the corresponding Masks

  • @danscourses
    @danscourses  11 років тому

    It was not professional Dave, it was done off the cuff in class with no script and no prior preparation, and it is free. I think everyone gets the point of my subnetting techniques even with the minor imperfections. Also, the point you are making is old news, I put an annotation note at the top of the video letting everyone know there is a mistake.

  • @danscourses
    @danscourses  13 років тому

    yes you could say that. When you subnet a network from say a /24 to a /28 (255.255.255.240) you are breaking the one network into multiple smaller networks

    Good apart from the fact that the right hand network is 192.1 when the left is 192.168. I'm not the best by a long shot, but surely the subnet isn't as important

  • @siwelanyer718
    @siwelanyer718 9 років тому +7

    Duh!! Double-Duh!!! I have always been able to see the powers of the "borrowed" borrowed bits. Ie. 128 & 64 place. Two bits. 2 to the 2nd power = 4. Four subnets. But what really drove it home is when you pointed out the position value of the 2nd borrowed bit, "magic bit", in this case 64!!! Yes! I see the light! I was using up a whole page of notebook paper on each subnetting problem. I can do them in my head now.

    @danscourses hahaha, It was there in front of me, Ive been working so hard
    to learn this stuff my brain had switched off.
    Id got the /25 CIDR Notation in my head (because thats what you started with on your white board)
    and couldnt figure out how they could be not ben on the same subnet, but to get the fact that /24 is 255 (one whole subnet), where as you where doing /25 which is 2 ;-)
    Thankyou so much

  • @doomkow
    @doomkow 13 років тому

    @danscourses So as I'm understanding this both switches/routers need to have the subnet of 255.255.255.240 and that automatically breaks the network up into block addresses that are easily chunkable and therefore easily on different subnets?

  • @pedrocamposnl
    @pedrocamposnl 11 років тому

    this explanation is indeed right if you consider having 2 networks then the correct answer is /28 but you wrote "all addresses should start with 192.168.1, i wrote 192.1.1 by accident Thanks to mikjet to point out " on the top of the video, then the answer /26 would be correct.

    • @RemixPicture
      @RemixPicture 10 років тому

      I know it was 5 months since you posted this comments, but I just had to point it out.
      You said "this explanation is indeed right if you consider having 2 networks then the correct answer is /28 but you wrote "all addresses should start with 192.168.1, i wrote 192.1.1 by accident Thanks to mikjet to point out " on the top of the video, then the answer /26 would be correct.".
      That is incorrect, because if you have two networks using the same IP addresses there can be problems. Imagine you have PCs with the IP 192.168.1.2 ans 192.168.1.3 on one network. And then you have the same IP addresses on two PCs in the other network.
      Now, if you were to ping from 192.168.1.2 to 192.168.1.3, you would only be pinging the PC in your own network. You would never get to the thetwork over on the other side, because the router would not know that you wanted to go there.

  • @linuxxxunil
    @linuxxxunil 10 місяців тому

    I was using the term “Least significant Bit” but magic number is way cooler. Totally lost about the 192.168.1 on one network and 192.1.1 on the other. How one network is subnetted has absolutely nothing to do with how another network is subnetted as far as I can tell. Thanks for enlightening us.

    Or does it depend on how you look at it? That is, rather, would we say: any less than 8 activated 1 bits in the 3rd octet are now considered additional bits that we've activated in the 3rd octet, having gone beyond the 2nd octet?

It's not even that big either, the most complicated thing on my network flowchart is the firewall of course with modified rules blocking specific IP addresses most of them located in China and India.
