19. How to Find the Broadcast Address

CCNA BOOST
Chap 5. IP Addressing

[@fanat41]

The most simple explanation I've ever seen instead of difficult formulas. Thanks a lot for the video, really appriciate to you

[@jamesfarlok4004]

Great job, I am preparing for the CCNA exam and your explanation is way much simpler and clearer then the official CCNA guide's one. Thanks a lot!

[@alexhill8700]

Studying CompTIA Network+ and spent a few hours on their Learn page trying to wrap my head around this. Your video made it so simple in under 10 mins!! Thank you!!!

[@CULTUREABOY]

You are a life saver. No matter how many times my teacher explained this, i just couldn't understand it and was beyond frustrated until now. Thank You for uploading and sharing. cheers.

[@johnwayne1287]

So much easier than what most teachers teach. Thank you

[@Wowezzersdozzers]

Thank you for the simple explanation. Everyone makes it so complex when its really as simple as this.

[@jamiearyan9058]

you prolly dont give a damn but does someone know a method to get back into an instagram account?? I was dumb forgot my login password. I appreciate any assistance you can give me!

[@bruceapollo9300]

@Jamie Aryan Instablaster :)

[@jamiearyan9058]

@Bruce Apollo I really appreciate your reply. I found the site thru google and I'm in the hacking process atm. Takes a while so I will get back to you later when my account password hopefully is recovered.

[@jamiearyan9058]

@Bruce Apollo It did the trick and I finally got access to my account again. I am so happy:D Thank you so much you really help me out :D

[@bruceapollo9300]

@Jamie Aryan You are welcome :)

[@henrydish100]

Very simple explanation. Thank you!!!!! Spent over 30 minutes trying to find help with determining the broadcast address.

[@CJ-si3ju]

I've listened to video after video with explanations that make no sense at all, i have watched everyone of your videos and it all just makes sense now. Man, you are a LIFE SAVER!! Thanks for the simple explanation.

[@StephanLamar81]

Thank you for simplifying it.!!!! I swear these Cisco books make subnetting so confusing

[@maddyahoueya5388]

This is what I called a good understanding of subnetting. You are a life saver

[@otaiko4806]

This video made finding the broadcast address the simplest ever. Thank you

[@yukihirasoma8167]

super easy but only because you're a great teacher I don't know why others can't just explain the math behind it math is awesome

[@erikasong3054]

Sir, thank you. I can't understand my instructor's handouts since he did not explain to us. Once again, thank you Sir! More videos to come.

[@phantombride05]

understood it easily within 3 minutes when i was stressing out for 2 weeks over it- :^)

[@marko514]

You are the best teacher in the world. Thank you

[@Kam_Jordan]

This video is still a life saver to this day, so easy. Thank you so much, hope your doing awesome!

[@rukshanaaly7794]

Hi there , in the second example isn't it Class B? because the value is in between 128-191 ?

[@jessicadan556]

Oh.my.heart! God BLESS you! I totally can do it now! Watched a bazillion videos before I found a system that works for me. And this works! Thank you!!!!

[@KingHill33]

the fact its actully this easy lmao. my teacher literally took 2 hours trying to explain this just confusing us more

[@aekpani]

I have arrived here for the same reasons! paying top $$ to university for substandard lectures!

[@dirtyharry205]

Teachers make it worse

[@erfanafshan]

Thank you verrry verrry verrry much. You are the best teacher ever...

[@joesnider5721]

Simplest and easiest way of subneting. Thank you for your time and effort.

[@Adjudicators]

The audio was a little rough but the content was clear and simple. Thank you for the lesson. Helped me study for the CompTIA Net+

[@paigeindysharp3409]

This is great! Really helped me in more ways that you could imagine. I was struggling so much and this method just CLICKED!

[@Sm3xy_Waffle]

Words cannot explain my gratitude, thank you for this.

[@rbondy008]

This is the best explanation of a broadcast ip. Cheers

[@richardtourangeau851]

Wow, c’est effectivement l’explication la plus simple que j’ai entendue, tellement plus simple que je pensais.

[@navarro145]

Bro thank you so much, this video and the other video for finding subnets are the best simplest explanations I've ever seen.

[@piagham665]

i watched more than 15 videos but this video solves my problem, thank you so much for the useful video!!

[@carine9200]

Very well explained but hard to digest. thank you sir you are the best in this.

[@xavierdereppe1142]

I never thought it could be so simple.... when explained as you do ! Thank you. Xavier/Belgium

[@Wigalicious]

this is probably the best explanation/method I've ever seen. Thank you so much. You sir have earned my sub.

[@MrToFlyTheG6]

The 1st time I’ve been able to answer these types of questions in less than 10 minutes

[@catarspot]

Thanks a lot, tomorrow I have an exam about this and i can finally say that i understand this, thanks a lot : )

[@ALESSANDRALEIHULIP]

You have the greatest lesson tutorial ever! I hope you don't die :))

[@seidgeniyu]

So much easier than what most teachers teach thank you a lot

[@matthewcardinal4186]

WOW! This guy just made this so simple. It made the other subnetting I am learning come together too. If you need to find the first and last possible IPs in a subnet, get the last by subtracting 1 from the broadcast. To get the first, subtract the "multiplier" from the "funny" octet in the broadcast and add 0's to any remaining octets except the last one, which is a 1. Well, all that makes perfect sense to me anyway. I love this guy.

[@tahersadeghi6773]

This method does not work. Adds confusion. Sorry.

[@megs69_420]

"finding the subnet broadcast address with a difficult mask" - start at 04:30 to save some time

[@michaelcedeno391]

Isn't the "172" example really 255.255.0.0 b/c "172" is a class B IP address? In your 172.16.20.20 example, you gave a subnet mask of 255.255.255.0, which is a class C 192 IP address.

[@simba1685]

Michael Cedeno 172.16.20.20/24 works fine, there is no such rule that says 172 can not have more than a 255.255.0.0 mask.

[@michaeldizon1641]

It should be 172.16.255.255 and not 172.16.20.255

[@maibagiangson4100]

@@michaeldizon1641 I was a bit confused until I saw this comment, all my questions were removed, thanks you

[@allukazoldyck3934]

Definitely right ..the second example is mistaken..the default subnet mask for a class B IP address is 255.255.0.0..And the correct broadcast address will be 172.16.255.255

[@michaelcedeno391]

@@allukazoldyck3934 thank you! I ain't the smartest dude out there! You make me feel a little intelligent today! Ha. Cheers!

[@shahadAlmajidisjourney]

Thank you! But what is the 1 subtracted? Why do we do that?

[@puya1342]

Thanks, but I see an exception which is not covered in your training, when the broadcast section value is already greater than IP section value. I still think the method in which one can OR binary form of inverted netmask (Wildcard) and IP, is the easier one to understand.

[@youssefelsafty4054]

the example in 2.41 is wrong because the ipv4 172.16.20.20 his subnet is 225.225.0.0 not 225.225.225.0

[@nmanikkumaar]

Very simple illustration ....you are genius

[@budddmj8191]

thank god for these videos. they are helping me so much!

[@chandrasekars7056]

How it possible class b ip address 255.255.255.0???

[@Uzii000]

oh my god thank you so much. its so much easier than my teacher explain it to me

[@catchwreck928]

GOD BLESS YOU YOU DESERVE ALL THE MONEY IN THE WORLD

[@levinfubex608]

thank you so much you explain way better than my lecturer ;)

[@strawberryicecream04]

Thank you very much, this has truly helped me with my exams!

[@siphilipe]

Study for knowledge not only for the exam.

[@lmarcelino555]

Omg this is the best explanation I have ever seen. Thank you.

[@stevejohnson3311]

You are awesome! Do you have any online classes for maintaining security + (Paid of course)

[@nmanikkumaar]

Super and simple explanation ...super Bro

[@evgeniibubolev9881]

OMG! How it could be so pretty easy??! You are genius.

[@tamahome99]

i dont understand .. You would only turn all of them to zero to find the netwrok address , then turn the remaining ones to "1" to find the broadcast id? i dont think its right because when i look at the other tutorials it says differently

[@Khazaro]

Simple like that? I'm learning about that during a few hours but I still don't understand, after watching your video I understand now Thank you for the explain

[@Nika-yp3vc]

Thank you, that was very simple (commenting this at 2.12am)

[@glennnorman8981]

This is awesome but what if the last octet in the IP address is zero and the mask is also zero, do we add 255 in the broadcast?

[@MacJ-NOI9]

If the number is greater than the number do i just take it away by 1?

[@MrXerolm]

For the second example, en.wikipedia.org/wiki/Classful_network, says that 172.16.20.20 is a class B network. So, the subnet is 255.255.0.0 . That's what I understood. Can you explain me this, please?

[@priyankabehera8288]

Yes you are right

[@yiskylee]

The train stop analogy can be a bit more comprehensive: say if you change 33 to 40 in the 192.168.2.33 example, then you won't miss your train stop, you would hit your train stop, but you still want to go to your next train stop, then get off. This is to hit 40, then go to 48, then do 48-1.

[@craigricker3720]

This does not work for the IP address 8.7.252.10/22 ??? It would suggest the broadcast IP is 8.7.251.255, but all the online calculators show 8.7.255.255..... what gives?

[@elsa1803]

Now, I understand, glad I found you, Thank you

[@bhootbangla5404]

How can i calculate the number of hosts & broadcast address using just subnet mask?

[@jeffersonsanchez5972]

but, what if the multiplier is greter than the number in the IP address, Ex. my ip is 165.132.9.0 and the subnet is 255.255.255.128. i cant seem to find the answer to the broadcast ip using that formula.

[@DanieleCappelletti]

Ty so much, that's the clearest explanation I've found!

[@vihanga193]

Thank you very much for this explanation I really love this thank you so much ❤

[@rmark1083]

This great explanation learned me something new! Thanks!

[@tumomabokoane3906]

wonderful my brother ..YOU ARE THE best then after finding broadcast so easy to find last host address .. can you help me on how to find network address.. peace

[@nannsuhtetsan7952]

omg such a life saver and comprehensible explanation! Thank You:)

[@legionsman7476]

I have a question asking for the broadcast address of a the network 172.18.118.64 255.255.255.224. According to your rule, the broadcast address should be 172.18.118.63, but I'm being told the broadcast address is 172.18.118.95. 256-224=32 32 goes into 64 twice (32+32=64) 64-1=63 172.18.118.63 What am I doing wrong?

[@legionsman7476]

I think I just figured it out: it's not greater than or equal to, it's greater than the funny octet. So, 32+32+32=96. 96-1=95. Does that sound correct?

[@gerryvalenzuela9158]

you have to go higher than but closest to it not equal to

An organization has a class (network of 192.84.7.0. It is sub netted with a subnet mask of 255.255.255.248. What is Broadcast address of Last but one sub network ?

[@saikiran-ku7fp]

192.84.7.0 belongs to CLASS C and the subnet mask is 255.255.255.0 and the broadcast address is 192.84.7.255

I didn't understood anything, nothing at all. I have a 200.15.0.64/26 class C ip so what's the broadcast and why?

[@ceylonperera1263]

Broadcast address 200.15.0.127

[@yanyant-q1l]

why 256 is used to subtract the 248
