I feel the topic which you guys explained about is not entirely adequate ,Since therein you have supernetted the IP address
220.127.116.11 to 255.255.254.0 ie /23 which is easy to understand
Though you should have also explained as to how you got to the values mentioned in the Supernetting/CIDR chart
Say begining with
/14 yields 1024 Class C networks
Now how do you get to the above values is it using the class A ,B or C network's
Actually I still feel there is a gap in the Explaination could Precise examples be given to figure out what you have put in the chart its all very confusing????
if you use the mask 252 in the 2nd octet of an ip address you have 2 bits left in that octet, plus 8 bits of the 3rd octet you have totally 10 bits free in order to build C-Class Subnets. That means 2^10 = 1024 C-Class Subnets.
If you continue like this, with the mask 254 you have 1 bit free in the 2nd octet and 8 bits in the 3rd octet, means 9 bits totally, means 2^9 = 512 C-Class networks and so on...
