What is the subnet? Easy Solution

[maxpolaris99]

Even with the 'mistakes' I found this video easy to follow , easier than my text . Thank You.

[BadNinja16]

Dude i've been trying for months to understand this!! and just 1 day of watching your video and i passed the test!

Thank you so much for the help!!

[BauerPower1nc]

Great Vid Dan. Ive been trying to grasp this concept for a while now, and this is the first time it "clicked" Well done!

[mybluemars]

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

Save my day :D

thanks mate



[sharrysharjeel]

u are awesome man.....thanks

[fear2me]

that's one hell of a six u created there! thanks man it helped allot

The video is wrong since the networks are on different subnets of 192.168.1.x and 192.1.1.x so /24 should work fine. I assume he meant that both networks are on 192.168.1.x in which case he would be correct and you need networks of block 16.

[danscourses]

@mikjet Yes I think you are right, all addresses should start with "192.168" thanks for pointing out the mistake.

[mikjet]

@danscourses Thanks, I am getting ready to take my CCNA exam soon and enjoy doing these.

[danscourses]

@mikjet I posted an annotation to let viewers know. Good job on catching that.

out of all the vids - this makes sense!! Thanks!

ever herd of subnet zero?

[relisys001]

Ive been asked a question :

Are the IPv4 addresses 192.168.1.200 and 192.168.1.24 on the same subnet, both have the same subnet mask of 255.255.255.0. I thought not as I thought 255.255.255.0 had 2 subnets 0-127 and 127-255 ? ?

Im told they have the same subnet, please help

[danscourses]

@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

[relisys001]

@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

[relisys001]

@danscourses

Ahh I know now, Ive been trying that hard to get to grips with all this, my brain shutdown.

As you were talking about CIDR Notation /25 initially in your vid, Id got I into my head that 255.255.255.0 was split into 2 subnets, hence why I couldnt understand why 192.168.1.200 and 192.168.1.24 were on the same subnet. I realise now that 255.255.255.0 is one whole subnet = /24 and /25 is 128 x 2 subnets, then /26 = 64 = 4 x subnets, obviously minus the network number and braodcast

[doomkow]

@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?

[danscourses]

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

[tmos222]

It took me 9 minutes to understand subnetting :)

[vempire23pk]

Amazing

i have watched Videos on youtube studied books

but this video gave me the understading of subnets

Thanks Dan you are Great !!!

[signalsoldier]

you the man! thanks a ton for this vid

[xyx2111]

What I like this video is, even he working past but the explanation is clear

Awesome videos, thanks.

[the147break]

didnt get at all

[pinkylinky4]

pls do u mind explain g where u got 47 to 48 becos the binary is 128,64,32 and 16 so the magic number moves from 0-15,16-31,32-63,64-127,128-23­9,240-255.

[danscourses]

@pinkylinky4 The magic number is 16 so the networks go up by 16 starting at 0. 0-15, 16-31, 32-47, 48-63, 64-79, 80-95, etc.

Also, in this video I made a mistake, because 47 cannot be a host it is a broadcast address 46 would be a better host address. :)

[theoriginalfatdonkey]

@pinkylinky4 2n-1, or n-1, 0 is a number u must count it, so 0-63 is really 64 get it?

[pinkylinky4]

u the best teacher

[nosleoj]

thanks you've just helped me with my coursework!

[Allip77]

nice video... easy for me to understand..

[mhtoori]

Nice Video Keep it Up Great
