Okay, I got my CCNA a couple months ago and am going toward my MCSE now....however, I haven't dealt with subnetting since my course material in Cisco so please forgive me .....
I have the McGraw/Hill MCSA/E 70-291 book and am covering subnetting. I haven't dealt with subnetting in a while....here's my question (straight from the book)
If you have an IP of 10.10.1.0 /23 how many subnets does this give you?
Well, wouldn't you take 2 to the power of 7 giving you 128? The book says the correct answer is 32,766.
How in the world do you get 32,766 when the 3rd octet of the mask has
7 networking bits?I'm either way off base or the book has had 3 wrong answers when it comes to subnetting which I find hard to believe. Please help me out here.
