Hi Francois,
For the ccna cisco works on the basis of classful addresseing rather than
the real world which uses classless addressing.
For your CCNA think classful and no use of the ip subnet-zero command

Subject: CCNA subnetting question [1:7459]
I have a question regarding to subnetting, as it is teached in CCNA.
This is about "subnet number can not be all 0's or all 1's".
I don't understand why?
For CCNA, do I have to know about the "ip subnet-zero" command which allow
all 0's subnet ?
But concerning all 1's, is for example 10.255.1.1/16 a valid host address?
Thanks for your help,
Francois.
