Heather and Andrea talk about different roles available for IT professionals and educators.
nice one
Thank u so much!! u r the BEST!!!! 😍🤍🤍🤍🤍
great tutorial 🤩
This is actually great, with some help from copilot AI i now feel confident in VLSM
Ur explanation for the last part was really bad didn’t get anything u said and u didn’t even explain how he numbers were moving up for the 3rd octat
god i love you
Your explanation is lot better than our lecturer.
Thanks you very much I did not understand my teacher style but your is so great
The best!
You explained this 1000% times better then my prof. Thank you <3 Gotta love finding a 6 year old gem of a video
i want to thank you once again @Andrea, upon several hours on working out why you got the 255, i've finally come into conclusion and decided to share with others here. 1. since the last digit is 0 we change it to binary of 2^8 (000000000) then we change all to 1's to (111111111) =256 2. for last usable address we subtract 1, so 256-1 = 255 NB: NOT ALL ZEROS WILL CHANGE TO 255,WE CHECK IF THE NEXT NETWORK ADDRESS HAS ZERO AS LAST NUMBER THEN IT MEANS OUR BROADCAST ADDRESS WILL BE 0, IF NOT WE SUBTRACT 1 FROM THE VALUE OF THE NEXT NETWORK ADDRESS
thank you very much however i have a question please, how did you flip and since we subtracted 1 from the 3 octet was there the need to solve and get 255 also if that's the right path please how did you solve and got the 255
Hello Andrea, I have a question concerning this IPv4 address of 172.16.181.23/19, how to find Address range for hosts on subnet ( first address and last address usable) ? Thank you?
thanks you so much
Merci beaucoup.
Thanks a lot
I love your videos, please more!!!
Thank u so much
Allen Betty Wilson Mary Brown Larry
Best explanation I swear more videos please
I still dont get how she 255 by subtracting 1 in the 3rd octet
Thank you soo much 😊
Thank you 🙏
Fantastic explanation of subnetting . The clear steps and example made it so easy to understand i finally got it thank you so much this video ❤
Who is here 2024 ? This is the best explanation of VLSM. Thank you 100%🙏❤
Not sure where you went, but your a great teacher. Thank you.
what do you mean by flipping the host bits on? i dont understand the second part
i am a first year IT Software Engineering student , we just started with VLSM and i understood little to none but after watching this video i have a full understanding, thank you mam , May god bless you and your family for offering free lessons on the internet , sending love from South Africa Port Elizabeth

Where did you get the charts
thanks Andrea for this video....
for someone who suffers with dyslexia, i found this very helpful and way easier to follow. Thank you
thanks
What a lecture
My life saver ❤️😭😭❤️
Thanks a lot, way easier and efficient when compared to my uni's
exactly what i was looking for
Hooo merci beaucoup ❤
You are a real life saver 🥺❣️ thnk u so much
this is the best
Thank you Andrea. Does this also work if you needed say "6 subnets"
Where did you get the last number from subnet mask 255 255 255, ex you said 240 and 192 where dod those numbers come from?
WHat will happen to the excess Network Address?
My greetings from Egypt
Thank you, ms.andrea for your wonderful explanation
Thank you so much for helping me understand VLSM. I've never had a problem with subnetting or FLSM however I can never wrap my head around VLSM. This is the first video that made it seem so simple. Now it's going to require a lot of repetition.
Hi dear Andrea thank you so much for helping to know this difficult VLSM you really made it easy for me you are really awesome🥰👍🙏
Good video! But, I've a question. What happen when need a subnetwork with 15 or 65 hosts? I think you must do 2^n-2 for a correct VLSM subnetting
Very helpful. Thank you.
<3
hello, if i have to add or substract 1 to get the various addresses, does this mean add or substract 1 to the last octet? because sometimes it is 0
