Thank you for the video. Can we then say that a Network Address will always have a 0 on the fourth octet?
Oh man, you are a savior. I have a school project and this video helped clarify how to assign those Vlans for my project. Thank you so much.
I love your videos man. My respect.
Thank you very much Mr this really helped me because now adays they teach us nothing in school thanks to your videos
@2:59 video time stamp, where did the 3 come from? Anyone?
Question. at 3:00 video time stamp, why did you choose to borrow three bits from the last Octec?
Great video. It still stands up over a decade later!
Very clear explanation. Thankyou!
why did everything just get deleted in the last one
Broo, you do good but your videos take longer time, i recommend you should summarize
That's great. It's helpful ... Thank you!
The link doesn't work anymore... any updates?
Didnt work

tres bonne vidéo j'ai adorer les explication mais j'aurais aimer que vous parler plus du rôle et du comportement des acl tcp established par exemple la commande access-list 110 permit tcp any any eq established a quoi sa sert concrètement et esce que sont implémentation peut bloquer une connexion ssh ou telnet a mon réseau local puis que c'est une conexion d'extérieur vers intérieur
Thank you so much!!!!😀🥲
great way to explain it!!
Such an insight video. Thank you!
how many subnets and hosts does the network have?
Whats that amazing Simulation Software
Hi
Thank you :)
thx
12 years later in 2024, this video helped me very much... Thank you
But is the answer you get wrong or not in the optional answers?
🎉🎉🎉
In case anyone wonders - the "Cloud" is just an image over the crossover and only represents the internet.
I have one problem during the tutorial. I thought the command prompt would do all the commands to the letter, but there was no folder 'samba' after typing in all the commands. So, the GUI directory didn't show one, made one myself, but there was nothing in it, no line like the example through the command prompt.
Thank so much ❤
Thank you so much!
Your website is down
Thank you so much for such an easy explanation
