I'm absolutely mindblown that anyone with this kind of knowledge and tutoring skill is sharing this course for free on youtube. No ads, no commercial plugs to buy this or that... It is absolute gold content and by far (and I mean really far) the best Azure instructor I've come across on the internet. High production quality (sound, lighting, instructions), to the point and well organized. I've watched the whole AZ-900 series and the cram, now going through specific parts again. Planning to take the AZ-900 this week or the next.

Thank you, that is very kind 🤙

This guy deserves a life full of wealth and happiness. I don’t think he understands how useful his lessons are.

[@DutchObserver]

SO happy with the recap in the end. This was by far the toughest lesson for me yet, having virtually no prior knowledge about networks. Still you managed to get all this knowledge into my head. You have my respect John, and my deep gratitude!

[@NTFAQGuy]

Glad it was helpful

[@rudyMents]

This is 22 minutes of gold. Huge help in getting a high-level overview of Azure network resources

[@pilgrim1536]

Just passed my AZ-900 with a score of 820, thank you John for your simple explanations!

[@NTFAQGuy]

Congrats 🤙

[@DemiKrueger]

This is one of the sections I feel the least confident on but this video is so helpful! I can finally understand the difference between private and public endpoint 😁

[@kalicharankhetwal]

Amazing session. Cleared up the basic concept of Azure networking. Thank you John.

[@jimklarp4957]

This one and all your videos are fantastic. Thank you so much for doing this!

[@JK-qz1sw]

The longest 22 minutes of joy in my life 🙂

[@NTFAQGuy]

Lol

Great instructor, great content. Thank you!!

Dude is a legend.

Amazing session. Thank you John!!

Nice video and enjoying the series so far. Got a little confused when you mentioned losing 5 IP's per subnet. Network and Broadcast address are default (2 so far), then you mention DNS and the Gateway addresses which results in 4 total. I've never seen 256 regarded as anything except purely from a mathematical perspective in network course. Is this a Microsoft thing? I am reskilling from a Network Engineer so I am very Cisco minded if that helps! 😄

[@NTFAQGuy]

2 DNS servers

[@KieranTheWalsh]

@@NTFAQGuy Thanks John! That makes sense. Fab course by the way :)

[@BHFamilyfull]

Ho John, thank you very much for sharing your knowledge, really appreciate! Best regards

[@NTFAQGuy]

My pleasure!

So I have a question on a detail - you have to make sure your Vnets don't overlap in terms of CIDR ranges. Is that because they *cannot* overlap, or because they *should not* overlap because it's a bad idea? I'm coming at learning Azure from a competing major cloud provider, and I know that there, you *can* have them overlap if you want and I've actually run into a use case to do this before.

[@NTFAQGuy]

They can overlap but you wouldn’t be able to peer them.

[@Cloudninja1]

most amazing channel

[@NTFAQGuy]

Thank you!

[@francis2k488]

Thanks, John. What is your hack for knowing this much about cloud technology? You are too good.

[@NTFAQGuy]

Lol just time

[@tawandachristopher]

thank you for this, fantastic work

[@NTFAQGuy]

Glad you enjoyed it!

John, around 5:40 there's one small inconsistency. You say that "you always loose all zeros all ones for network and broadcast address". This is a mispeling I believe. Broadcast is the last ip in a given range (255 if the mask is like /8 /16 /24). The other thing is with this "zeros". It is true again with network masks /8 /16 /24. But with other masks not exactly. In fact it is "the first" IP in a given range whatever this first IP address is. And same with other IP addresses taken by Azure. So all in all properly it should be explained as Azure is taking always first (network address), second, third, fourth (def gw, dnses) and last IP address (broadcast) from a given subnet range. I know that for the simplicity of explanation it is most commonly explained as .0 .1 .2 .3 .255 ;).

[@NTFAQGuy]

Broadcast is all 1s in the host space, ie all bits set in host portion. Watch my video on ipv4 subnetting for more info.

[@walatd]

@@NTFAQGuy oh...., now I see, I've misunderstood what you are saying in the video... all zeroes = 000000...., all ones = 111111.... (in hot space) - my bad ;). Now it pretty makes sense.

Thanks

You are a genious!

[@NTFAQGuy]

Lol, far from it :)

[@Santalucesguy]

So easy to grasp… crack!!
