Subnetting Made Easy Part 1

127 is reserved.

I still have something I can't get. My isp assigned address subnet mask is 255.255.255.0 by the rule of subnetting this means I can divide the last octet into subnets but my ISP gave me only 1 address so it's obvious I cant'make subnets. So why my mask isn't 255.255.255.255 instead?

What happens when you subnet for thousands of hosts? What would subnet 20 be :)? I only understand subnet for very few hosts - under 254

thanks b/c my German instruction is giving me the blues

i still do not understand the slash thing at the end. Can you explain more where the 26 came from?

I love you!

I love you too!

Subtract one bit to find the closest value! This just saved me from constantly having to do the long math 1+2+4+8+16...

wtf are you talking about? I did originally read the entire conversation. A classful class A network range is 1.0.0.1 - 126.255.255.254. 127.0.0.0 is reserved for looping back to your own network card.

Classful class A is 1.0.0.1 - 126.255.255.254. The whole 127.0.0.0 network is reserved for loopback, end of story.

jacob im currently studying networking. can you guide me more often?

WOW just an awesome explanation. Thanks so much!!!

Why does his first subnet start with 172.16.20.0 instead of 172.16.20.20?

I don't get it :/ were does the /26 come from? Subnetting is the only thing I don't understand correctly..

Great tip about how to count the values grouped on the right. Love that!

Great simplification to the way I was taught subnetting.  Great video series!

The closed captioning is badly garbled.  This will be useless to the hearing impaired.

6INFO ftw!

I completely don't understand...

SWEET!

thanks!

Thanks ! 

Im not sure the Subnet mask is correct even if you go from right to left you need 50 subnets. In this case you will be borrowing 6 bits from the fourth octet if you go left to right you have 2 bits of available host  so the value would be 11111100 = 252 the mask should be 255.255.255.252 Network should be 192.168.1.0 to 1-30 192.168.1.31 the next network id should be 192.168.1.32 .........

how do you find the broadcast using this method?

Ok, wow! Thank you so much!

Classless ftw. 

excellent for my exam next week

why does class A does not go up to 127? What is 127? Class A or Class B?

From all of the "so-called" easy videos talking about subnetting, this is the best and easiest to digest one. cheers.

Great Method !!! very easy to grasp! with this technique, I will be able to achieve subnetting in 30 seconds which is the goal our teacher gave us. I am very thankful for this video!! thumbs-up from me !!!!!!

I appreciate the posting I'm studying for my ICDN1, math is not my strong suit but this video really makes it allot easier to grasp!

Thanks!! only video i found was to the point

Amazing video, I took a Udemy course to try to learn this, but this video helps me learn process it quicker. I'd recommend this to anyone struggling with Subnetting like me. :) Thank you so much for making this video!

Our tutor gave three 4 hour lectures on how to do this; thank you for saving us

audio version of TLDR

Can you help me to divide this n/w id 205.67.35.0 in 3 departments where the size is equal of each department using FLS(Fixed length subnetting) we have to determine the mask of each subnet the broadcast address and network address. Also the number of hosts in each subnet...
Thanks in advance

Wow!!!!!! You have done extremely well for me. All my doubts are clear about subnetting  Class C addresses except for Class A and B. Please help me with the links to any of these Classes subnetting videos if you have. Thanks a million......

thanks a lot man!

Tyyyy

Poor voice. Does not seems confident. See how confidently Jacob Hess speaks. Why so many pauses???

I wonder if the world would be better or worse if we started teaching math in base 2 instead of base 10....

Thank you

<3

This is absolute gold!!! its made something so easy to take in, previous videos/ books just complicate the process unnecessarily 👍👍

As an IT manager who's a little rusty on networking, this is gold!

My 7 year old self won’t believe he will learn this 14 years later

You're a genius!
