Would just like to say that I have been struggling with this VLSM for a couple weeks and your 15 minute video made me understand it. Thanks for putting this video up really helped me understand it! :D
Thank you so much for this. I never really understood subnetting in class and most of the time i got only a few LANs right. I have a subnetting test tomorrow and now i'm quite confident that i'll be able to tackle it :)
Why is it , that when you got to LAN 7, you started with address 192.168.10. 208? then you jumped to 192.168.10.224/30. I got lost at that one? help...
Subnetting is the same no matter what class. The idea is the same the only thing that changes is the number and the octet that you might be working in.
Each Network wil be having its own router as well. What about the IP address for the routers.
Mean to say that u should use " 2* - 3 " instead od " 2* -2 ".
Specially in the server network, u have two servers & one router to take servers out of their LAN; means 3 valid IP adress & u can't have 3 VALID IP addresses from 2 bits. U HAVEtoHAVE 3bits to get at least 3 VALID IP address (as one will go to your router which will take u out of that servers LAN / LAN portion on which ur two servers are)
man your awesome, you just taught me something that I have been trying to learn from my professor who has taught this over and over again but I didn't understand, thanks man!
one thing im not sure, on the Lan 7, there are two servers plus 1 Router....so there is a need for three ip addresses on Lan 7...but you have used just two ip addresses...what ip address do we assign to the router then?
thank you SO much! my ccna 2 final is tomorrow and ive been stressing so bad over vlsm and watching these 2 videos totally made my night, you're a great teacher and thanks for your help!
What i don't understand in this video is that for LAN 7(server) in which you need 2 hosts WHY did you start at 192.168.10.208, shouldn't you be starting at 192.168.10.224
man seriously i didnt know anything about VLSM up untill now. U MA MAN JUST MADE MY LIFE...seriously NOW I MA GO UOTO MY F'KIN PROF. and TELL HIM WHO'S THE MAN NOW BIYATCH...LOL
but all thanx to u ma man for uploading this video...really really thanx
how about if i have to split the first subnet /26 into 2 parts? can i leave the other networks and just use the /27 subnet which fit in the first /26 subnet
hey dude i think at Lan6 last ip address was 192.168.10.224
so Lan7 must have 192.168.10.224 right ?? correct me if im wrong?
Btw nice Tutorial :)

In the real world, however, this would probably be a 10.x.x.x network with NAT overload through the router or firewall.

What i don't understand in this video is that for LAN 7(server) in which you need 2 hosts WHY did you start at 192.168.10.208, shouldn't you be starting at 192.168.10.224
rockynaruto 2 years ago
no wait...you just have a minor typo there i think...on beginning of LAN 7 side 192.168.10.208 which should be 192.168.10.224 hmmm OK
