RichTechGuy - Thank You / Master level explanation of the IPv4 Construct and how it is practically implemented. I struggled with this concept until you brought clarity. I knew that I could manage my way through Subnetting however I did not consider myself good enough to Finesse the working details as well as explain, as you did this with little effort - Kudos. I am so glad that I found and subscribed to your channel I will pick through your playlist with computer and popcorn and a drink to enjoy the learning. 🤓 Again thanks for making this topic less than a headache for all who care to watch the video.

Your explanation was too good. Thank you so much for this video. You made subnetting so easy to understand. 🎉

I bet your room acoustics would work better if you spread those sound damper panels around on the large flat wall surfaces in your studio. Thx for the subnetting video.

Thanks for this great video! I do have one question I'm struggling with: I'm using your tool and and have an ip of 115.163.109.207 and a subnet mask of 255.255.248.0. I get everything right but the broadcast IP address.

The solution per all the calculators I've used including yours give 115.163.111.255 as the broadcast address.

In the example in your video, you have 172.16.15.25 and subnet 255.255.240.0; The broadcast address works out as follows:

Broadcast:
Broadcast Address: 172.16.15.255

Well that makes sense, the 1111 = 15.

But, in the tool when the problem is an ip of 115.163.109.207 and a subnet mask of 255.255.248.0, the broadcast address portion of the third octet is I would think 111 =7, as in the your video example, 00001111 is 15, but apparently it's 111 and I have no idea why. Can you give me any clarity? Thank you!

The entire 127 range is reserved for Lookpack... A 0.0.0.0 - 126.255.255.255 / B 128.0.0.0 - 191.255.255.255
