Bruh I had like 1 day left to create an entire presentation on IP addresses, and I was so confused. Legit nothing helped me, I couldn't understand anything anybody else was telling me. You are my savior, kind sir. I am forever in your debt.
Thank you Mr.French, your explanation brings it back to the basics without disturbing calculations pictures and numbers but with mentioning the technical reason for it. This gives me the chance not to forget it. Thank you!
Thank you Greg, this was a wonderfully explained video. I don't mind your small refreshers on things like binary and ANDing because you explained them very carefully, and nothing was missed if one skipped forward a bit. Great video, and you really talked about what matters instead of what doesn't.
Very good explanation. I now fully understand subnet masks. The only downside is that u made an error for the Class B subnet mask. The example that was used is a Class C default subnet mask. Class B = 255.255.0.0 while Class C = 255.255.255.0. Still a good video however and I now have a better understanding. Thank you!
@ 8:50, my life got turned upside down. All these years I had no idea. Best explanation ever. 25 years old and dealing with computers all my life and finally, it makes sense.
A router does not typically use a subnet mask to dermine a host portion and network portion. The only time it might use one is when it is sourcing a packet. The router utilizes the subnet mask to determine whether the destination address of the packet is on the local subnet. The router still uses subnet masks stored in its routing table to process packets but not to determine a host and network portion.
I really like how the video straightforward explains the subject matter at its baseline without bringing too much technical jargon into it. Is my basic understanding correct? Subnet purpose: make networks more manageable and prevent them from overloading with too many users/machines. Subnet mask purpose: Allow a computer to check whether another computer is local or remote.
Break up broadcast domains. Also logical isolation. If there is no route between two broadcast domains then they can not communicate. They are isolated.
The classes of Subnet Masks at 3:49 shows Class A using 255 in the first octet, Class B using 255 in the first and second octets, and Class C using 255 in the first, second, and third octets. At 6:40 an example of a Class B shows 255 in the first three octets. Why is it not 255 in only the first and second? Wouldn't that be a Class C example?
You need to look at the binary numbers to understand how the computer uses the subnet mask to determine the network and host portion of the address. Hope this helps.
the default subnet for class B is 255.255.0.0 but in the second case he kept the custom subnet mask for the given class B address. It is bacause 8 bits has been borrowed from the host portion to subnet the given IP..
So the subnet masking is a bitwise function essentially in order to separate what nodes can see as a security measure but also for segmenting the network jobs. A router needs to assume as few responsibilities as possible to speed up the network. A small router with minimal processing power and less ram needs to deal with smaller instruction sets.
I don’t understand what the three cylinder shaped things are with the different numbers in the third octet?? Are those the routers? I thought routers have a 1 as the last octet?
Would be better if you have explained some about the use case scenarios of the different Class of subnet mask addresses. I only see about the class C type of subnet mask everywhere. Also, the customizable nature of the subnet mask , that one can assign class C subnet mask to a class B IP address. I enjoyed the video though. Thanks
I'm confused a bit. If you create 2 logical networks from the outer network, so the two subnet's IPs are 135.68.2.0 and 135.68.3.0, does that mean the first three octets of the subnet mask make up the network address, and the 4th octet is for the host addresses, and therefore a class C subnet mask?

Bro me too
Thank you Mr.French, your explanation brings it back to the basics without disturbing calculations pictures and numbers but with mentioning the technical reason for it. This gives me the chance not to forget it. Thank you!
Yes, Mr. French, I've researched almost 50 of these videos to get the best explanation, and
yours is the best! Thank you!
Thanks for the comment.
You did a great job on explaining it better from all. I look forward for all network topic to understand.
Thank you Greg, this was a wonderfully explained video. I don't mind your small refreshers on things like binary and ANDing because you explained them very carefully, and nothing was missed if one skipped forward a bit. Great video, and you really talked about what matters instead of what doesn't.
Very detailed and useful. Thanks for a high quality explanation!
This was the best explanation I have seen and really stuck, thanks.
Great and simple explanation. Thank you Greg!
I just started learning Networking stuff, thank you for this video. Very clear to understand and easy on the ears.
If you already understand binary then this is by far the best explanation. You, Mr.French, are getting a new subscriber.
This is the simplest break down on how the network portion of the IP correlates with the host portion of the IP, thanks!
Very good explanation. I now fully understand subnet masks. The only downside is that u made an error for the Class B subnet mask. The example that was used is a Class C default subnet mask. Class B = 255.255.0.0 while Class C = 255.255.255.0. Still a good video however and I now have a better understanding. Thank you!
This is the best tutorial I could find on the topic. Thank you. You take a complex concept and make it simple as possible.
Great video, was a bit unclear at 6:30 but comments and repeated listening got me through it. Thank you!
Your voice reminds me of Jeff Goldblum. Thanks for this video.
So true 😂
Bravo
Lol. Life finds a way
Must Go Faster
Oh man spot on
@ 8:50, my life got turned upside down. All these years I had no idea. Best explanation ever. 25 years old and dealing with computers all my life and finally, it makes sense.
I finally understand subnet masks. Greg you're a god my guy.
Thank you for taking a confusing subject ( confusing to me anyway) and breaking it down part by part into something that is actually understandable.
Thanks for the explanation, the subnet masks make so much more sense now.
Thank you, Mr. French! Excellent! Great teachers break it down to the easiest level!
Best explanation I could find - amazing, thank you! 👍🏻
I wish all mysteries in life were this easily explained! Excellent video!
Thank you Greg!
Tq sir for the explaination.. You are the best explainer that i get and easy to understand.. Much appreciate it!
Very clear explanation. Thank you very much for going into detail of the filtering process.
RIP i just noticed in the comment sections he passed away :(
A brilliant video, it really gets to the point without getting lost .
Thanks for the comment.
YOUR SLOW PACE HELPED A LOT
Great vid, really tied some concepts together for me
This was a big help. Much appreciated.
i have been asking this question for 30 years. now i understand . TQ teacher
Thank you ... your a great teacher!

Thank you, very clear explanation. God bless you!!
Thanks Greg nice video, helped me a lot to understand the subnet mask :)
Thanks for a great Video! - to the point and easy to understand.
easy to understand , simple explanation best video for subnet
This makes a lot of sense. Thank you so much!
Great explanation, really helped me understand this.
awesome video, nice explanation, easy to understand 😃
What a fantastic explanation. Thank you.
I had to rewatch / re-listen a couple of times, especially at 6:00 to 8:00 ish, but damn this is an absolutely excellent tutorial.
Thank you sir for this tutorial. It was very usefull.
Excellent tutorial, many thanks for sharing
Great vid. Thank you!
Its like a filter, thanks man :D
every body can not be a teacher but you sir have qualities of a teacher excellent!!!!..I learned something and thankful......
thank u
I'm really thankful cause i searched all the net for a simple explanation found none
Very helpful. Thank you!
God bless you Greg.

Yes, it did help. Thank you!
Thanks alot buddy...u helped me alot...i don't know how to thank u...
Very thorough. Thank you.
I finally understand!.. Thank you so much!
thx so much Greg u a legend for this
Clear explanation. Made sense thank you

KlevonOfJesup you right
subnet is just a filer
Fantastic video, thanks heaps!

You made my day brother

you make all this sound so easy.
thanks excellent presentation!!!!
Excellent teaching.
hello, so on the first illustration you showed, what's the mask of for example the IP 135.68.1.0 ?
Such a great video
This was helpful.Tnx
easy and amazing, thank you so much
Finally I get it, thank you!
Thanks for the video.
Awesome!!! Excellent!!! Thank you!!
why you added subnet mask of class c range
Thanks, Greg.
Your very good teacher
Thank you a lot!
thanks for you video!
Thanks for this video
How is localized sub addresses going to be handled with version 6 ip’s?
Good insructer thank you so much 👍🏻
that was great. to the point without the channel branding stuff. thanks very mcin
Helped alot, thx
How to access multiple bio metric devices remotely through WAN ?
very much helpful. Thumbs up
How can every pc have unique ip when there is nas?And also,when we subneting,we subnet the local ip that the router give us or the ip of the router?
Do you think this system will eventually be scrapped or revamped in the future just how IPv6 is taking over?
This makes so much sense now....
Thanks Greg.
Is this why DHCP was invented? So we could avoid having to calculate the network IP address after assigning a subnet?
DHCP was created to solve the burden of having to manually configure each interface.
thank you very much.
Sir, is subnetting done only for private networks/IP's? If it is also for Public Networks/IP's, then how it is done for such networks (public)?
Couldnt ask for any better
how you determine the mask I dont understand yet! at 9:17
easy way thank you for this video
I'm confused a bit. If you create 2 logical networks from the outer network, so the two subnet's IPs are 135.68.2.0 and 135.68.3.0, does that mean the first three octets of the subnet mask make up the network address, and the 4th octet is for the host addresses, and therefore a class C subnet mask?
Can this help you to not get ddosed since it splits the ip into different parts?
this is amazing video Ezxprt is also IT professional Academy
Nice and simple ..thanks
