thanks a lot for explanation. Does flipping the 7th bit always mean adding 2 on the second digit? For example, 1C becomes 1E, or 3B becomes 3D? If yes, then we can also say, insert FFFE in 1st and 2nd half followed by adding 2 to the second digit of what you get? Thanks.
So if the mac address didn't start with 00 and instead had a number or letter, or was something like 09:XX, I would flip the seventh bit and either add or subtract that number to the total, giving the new value? So if it was 9, that would be 1001, which would flip to 1011 and the new total added together would be 11, which would be represented by the letter B (if im right) and would then be 0B:XX? Or am I wrong and the second value will always be either a 0 or a 2?
I'm having trouble understanding why you put a 2 in the mac address: 0215 in Step 6. They were 0000. I'm not quite understanding that part yet. I would appreciate it if you could explain that more. Thanks.
because he flipped the 7th bit and made it a 1. that 7th bit is rested inside of an octet.. so that 7th bit's value is actually either a 2 or a 0, the fact that it is flipped "on" means that it takes the value of 2. if it were the 8th bit, it would be a 0 or 1, if it were the 6th bit it would be a 0 or a 4, etc.
Thank you for exploration. But this example was too simple. What will we have if mac-address starts with AB(for example)? It's will quite hard to calculate in mind.
Better explanation that the official ccna material, thanks :)
That music at the end scared the shit out of me. Great video btw.
Haha same!
Thank you so much… read this topic in the CCNA twice and I’m like….. this video helped so much
Very nice and easy to understand. I think this is the kind of thing that once you get it you will never forget, sort of subnetting :)
5 useful minutes on TH-cam. Thanks for this video.
Thanks for this explicit explanation
Best explanation thank you from Algeria 🇩🇿
Thanks for all the effort! I love your videos! May God bless you!
ALOHA
WOW!! that was the best explanation iv ever heard
MAHALO
Awesome video and great voice!
Your voice sounds like Ron Swansons :)
Thanks for the vid.
Very helpful in solving my Assignment questions. Thank you

Thanks a lot! Helped me out for my final exam! :)
Thank you ! Great explanation!
Beautiful.... Good job Kevin
very nicely explained. excellent graphics as well. thank you
Vivid explanation.Thank you so much
Oh yeah it really helped. I'm glad i can now calculate the interface id with no fear. thank u so much Kelvin
Thank you!!!!Great refresher for my routing class!
very good info, wish there was one on the hexadecimal to binary conversion
Thanks for clearing my doubt , much appreciated
That was extremely helpful thanks.

So informative. Thank you!
Very nice explanation!!Thanks
nice
What if the original 7th bit is not a zero....how do you flip it?
If it’s a 1, it flips to a 0. If it’s a 0, it flips to a 1.
great video
