Hi Eli, good to hear or start to hear your information. I appreciate your return to the basics. I hope you get a lot of response to your Dojo.

When you need to know it, you NEED to know it...but you generally don't need to know it. The best explanation I've heard of IT since the first Eli video I watched.

Eli, I am still here at the end. Great information. I am glad I am retired. I created IP addresses for devices devices to keep a logical numbering system. It did not comply with any proper order;. If I knew this before, I would not have messed up so much to try to make the numbers logical based on areas. I did create different networks by accident. Great information I wish I had back then. Great information.

Perfect timing Eli. I have a test on Tuesday and part of it is on Subnet Mask. Thank you!

It's weird, I mean I know it's 2022, but we have some old school Eli going on here. Good stuff.

There are 10 types of people in the world ! Those who understand the binary number system and those who don't !

Quite informative, the basic principles are relative to that of musical understanding, and glad Eli, you've explained Octets.

I ran into subnets that violated an RFC, a firewall was a Sun (that allowed illegal subnets) it had 4 interfaces (internet, company network & 2 business2business zones. I found this out trying to fix a routing problem. Most of our unix hardware was HP9000 and it did NOT allow the illegal subnets. The bosses were very snippy about having to admit to a customer that we (consultants made for us) a mistake and needed to adjust a subnetmask and change a server IP address.
