I've been reading for the last hour trying to understand what I just learned in your 3 minute video. Thanks so much!

We need more "rapid" tutorials like this.

I troubleshoot a network and was looking for a better explanation of how subnet masks play a role in data getting to its destination. This is the best I've seen. Thank you very much.

7 years later and this is still the best explanation on the internet. Thank you!

[jamesknight]

Most networking has terrible explanations but this was fantastic. Thanks!

You deserve a freaking award.... I have no idea why all the resources I read can't be as simple as this. Thank you so much

i have spent half an hour reading the cisco explaination of this and got nothing but a headache, your 2 min video has cleared it up. thankyou !! life saver

[Firecrak]

Great explanation, thank you!

The key to understanding for me was the bit where you mentioned machines that the host can go to directly, rather than querying the gateway.

Excellent and Simple. One of the few videos, to make you understand the concept of a subnet Mask! Videos like these and folks like you.. make YouTube worth watching.

Wow been reading on the internet the the last hours on subnet and all I got was technical explaining of how it works, but no explaining of how it really works, aka what's the purposely. Watching.your video cleared up everything for me, now I can go back to the technical explanations and it makes complete sense now. Thanks!! Please make more video when you can

This is 5 years old and still helping people. Thank you for taking the time to explain this!

[colonelvector]

Great explanation, one of the clearest and simplest I've heard yet

Damn I've seen long videos where they talk about random stuff but dont actually explain wha the subnet mask is. And you just said it quick and clear XD. Nice video.

[davidswift]

Simply explained. An explained diagram makes all the difference. Many thanks mate. :-)

[ruthlessadmin]

It's not that I didn't understand basic subnetting before watching this, but I didn't understand the purpose in a specific situation. Now I'm starting to get there. Thank you.

I've been trying to understand subnet masks for the past hour but you just explained it thoroughly in 3 minutes! thanks!

My teacher told us to put definitions in our networking project. One was subnet mask, which he had never taught. I've been so confused trying to figure this out! you made this so simple thank you so much

[Prophint]

this is the ONLY video that's made this concept click for me. Thank you!

[CrayTheZ]

I just read an entire article from Microsoft about subnet masks and felt even more confused after reading it than before! This video, however, made things crystal clear and was very well thought out! THANK YOU!

[danishbegmirza]

Wow!! That is such a nice explanation of Subnet Mask! Thank you very much for this clarity! Somehow, a hundred videos have been unable to explain this previously.
