[@danscourses]

You are welcome. Thanks for the feedback!

[@warrenlogan3918]

pro tip: you can watch movies on flixzone. I've been using it for watching all kinds of movies recently.

[@brycenchad580]

@Warren Logan Definitely, have been watching on flixzone} for since december myself :)

[@locodragon3994]

hey dan, thank you for helping me remember how to do this, and make it in a way that was understandable. I really appreciate you!

[@yutanalee3463]

You are my teacher. You have a godgift to teach complicated concept to students. I'm CCNA but confuse VLSM until watching this your video. God blesses you stay healthy. Thank you so much.

[@CitizenPerkins]

WooHoo! That was a pretty good refresher quiz (for me!). Thanks! 👍👍 Looks like I can still do VLSM with the best of them! 😁

[@danscourses]

Ha! Gotta stay in practice!

[@maxxp4in373]

Thank you so much sir! This video was very very helpful!

[@daluppo6961]

Thanks, watched this one day before my exam and nailed that shit

oh my god this guy saved my life loooooooooove youuuuu

[@JDrum7]

Great Video! 1st of all and Thank You. I get caught up sometimes on counting the host bits starting with the 2 ^0 value 1st rather than starting at the 2^1 value giving you two hosts. Is there any main principles or ways to help remember that and distinguish between thoses counts?

[@williebrown4266]

Very excellent refresher.

[@geysagalaroff1778]

Thank you Dan. Very good explain.

Question: Why did you not use a /31 mask for the point-to-point connections?

[@h.fontanez5453]

This is gold Dan, thank you. Have you published any books?

[@danscourses]

Thanks. Not yet. Maybe in the future...

[@siucbset]

VLSM: Do you have any videos where you do reverse VLSM? Example: You go from 8 subnets to 2 subnets?

[@dolores0h4ze]

thank you man

[@therealajmelmuadz]

thank you bro

[@destinyoce]

Thank you legend.

[@TheBeach5563]

This is awesome. So how may videos do you have in this series on subnetting. I want to go through the whole series.

[@danscourses]

Hey Robert! I will need to count and maybe make a playlist for just that. I have made a lot of new videos on subnetting and I have lots of older ones too. As you know.

[@TheBeach5563]

@@danscourses oh yea thats right. Sounds good.

[@danscourses]

Here is a link to my new CCNA 200-301 Playlist which I am compiling as the year progresses: kzbin.info/aero/PLndqfxA_9SWEH6AHP9djFhqq7NAqClNyb

thank you

[@aflyingtoaster6096]

short and clear

[@calismakicin8444]

Thank you Dan

[@danscourses]

You are most welcome!

[@Sir.Barson]

Thanks Dan. Quick question, is the network block class B Or class C?

[@danscourses]

the number 172 indicates Class B however this is classless addressing because our subnet masks are not restricted to /8, /16, and /24. So speaking about class doesn't apply with VLSM

[@UmerKhan-ro3dy]

Thanks ❤️

[@huangzeyong]

good video

[@descobra5462]

Hi so its always 2 hosts between the routerd if its not listed? Because i saw one where there was network ABCD with host but EFG that was between the routers had nothing

[@danscourses]

Depends on the requirements of the network or the question.

[@descobra5462]

@@danscourses is it possible for me to post the link of the exercise for to see? Cause i am bit confused of why they used 2 hosts

[@danscourses]

@@descobra5462 is it two usable hosts /30 or or two hosts period /31?

[@danscourses]

I have been informed that with serial connections ISPs will use /31 subnet masks. Which seems weird to me because that is only a network address and a broadcast address but in a point to point serial network I was told it does not matter. Probably not you situation though

[@tanvir7783]

Thanks

[@fuglesang146]

How can you avoid waste alot of host space when configureing 100 + 55 it is a bit difficult without wasting alot of host space. And should you always start with the largest network first?

[@foxxrider250r]

Yes start with the largest always

[@aadilhussainmir4947]

How should be / 24 to the given ip as it the class B ip address.

[@Ibrarahmad-qf3rn]

its awesome scenario but sir if you have time i have one complex scenario which given by teacher as exam if you would like to have a look or try it will be glad to share it with you and i did it but still i have confusion somehow i am not feeling so satisfy with it so if you explain with video it would easy and help full its CLO3 question
