CCNA CIDR subnet review

This is designed as a quick review for people that already have at least a general understanding of IP addresses, addressing, and subnetting.

This was done a while ago by request to help someone who asked about it.
Hope it helps a few more out. If you're confused, ask away... as usual.

Excuse me, I have a problem about how to get the list "0, 64, 128, 192" on 7: 04

would you please further explain it to me? Thx : )

@voilethht Sorry man I havent been getting messages on comments apparently.

The way to get the list is to manually write out the bits in the octet, like in 2:24 - then once you have that then back to 7:04 you are borrowing 2 bits from that last octet which brings you to 64 (64 is the 2nd bit in the octet)

Hope that clears it up a bit

Hey thanks for the refresher. I graduated with an associates in IT, but I have a job in logistics. Nonetheless, I have to move and switch jobs and I will be doing IT work. So I will venture in review for a month to shake off the cobwebs and get back in the game. Again, thanks.
