IPv4 Addressing - Subnetting (Part 4)

In part four of this Ittaster video series, this tutorial explains #subnetting, demonstrates basic subnetting techniques by working through a subnetting example, before moving on to 'variable length subnetting' and 'variable length subnet masks'. #IPv4

Say hi on social:

Fantastic explanation of concepts related to IP address and related terminologies. I enjoyed watching all 4 parts. Many thanks for these videos.

Perfect Explanation of the Subnetting Concept (and the other concepts you introduced in the other 3 videos).

I had taken Networking as one of the Subjects in my college many years ago, Loved the subject, but never really got to work in this field professionally at work. I just Started looking at your videos as a refresher and found them fantastic. Please continue to make more of them.

Its a Shame these videos don't have more views and likes they deserve.

Thank you so much for sharing John.

Thanks a lot, all four videos have been really helpful, you deserve more views.

Interesting series, I enjoyed it. Thank you

Thank you, I also like your "Configuring User Home Folders - Windows 2008 R2" video that help me before.

Very resourceful videos
I was reading few book on Kindle to understand it but your video solved mystery for me

[yakubpash]

John u r videos helped me understanding basics of IP and subnetting concepts, if possible can you share ppts to us.

you have mentioned in 13:55 that the first subnet network gives you 126 valid host adresses how did you do it

[geoffchadwick]

Hi John thanks nice video, can you explain why we don't just simply change the the address from 192.168.0.0 to a class B address then we gain more addresses right away or am I missing the bigger picture.

Another question or just the above rephrased : Would it not be the same thing if you had a DC on each site that was set as a sub domain of the main DC at HQ so that each site would have it's traffic circulate inside the site via the onsite DNS and only connect via HQ if the intended host was not found in the onsite DNS - effectively doing the subnetting. So if I am understanding this and if I am correct - subnetting eliminates the need of extra DC or DNS onsite or how does it eliminate extra traffic in a way that would be more effective than just having DC's and DNS's onsite effectively handling routing?

[fabianhall]

is there a part 3? I can't find it in your videos

[geoffchadwick]

hi Jon, ok more subnets but why? what is the advantage.

[jonoseven]

or would you have to use more DC's and DNS servers to handle networks that are divided on the 3rd octet 0.0.1.0 ? is that why ya'll subnet?

[jonoseven]

If it did make sense then people would be doing it, maybe they are? Could one not just simply 192.168.0.1 a network and "subnet" via 192.168.1.1 and use a router connected to a DC with DNS to rout the traffic between networks or is it better to subnet, forgive me but I don't see the locig in subnetting as 192.168.0.1 - 192.168.1.1 - 192.168.2.1 - 192.168.3.1 would give three different networks and you would still be using 255.255.255.0 as a subnet mask and retain 254 hosts each and the networks would still need a router to talk to each other as they are still technically "difference" networks as with subnets... -and not have to over complicate the network via subnetting via mask (255.255.255.196 etc) or am I missing something important that I am not taking into consideration in this post? I am still learning :)

Network range or space not “network address.”!
