- What range of IP addresses is represented by the CIDR block 172. 16. 0. 0 12?
Thus this block represents the IP addresses from 172 16 0 0 to 172 31 255 255 The netid is 1010 1010 0001 and the CIDR block contains 2^20 addresses * I fully understand that the CIDR block has 2^20 host ID addresses and that it is in a Class B network

- why private ip address need to use specific CIDR prefixs as 8, 12 . . .
why the CIDR prefix is 8, 12, 16 respectively? why the CIDR prefix is not 8, 16, 24 which matches the prefixs of Class A, Class B and Class C respectively? You are mixing Classes with Classless Inter-Domain Routing (CIDR) CIDR means there are no classes, so CIDR does not need to respect classes Forget network address classes, they are obsolete since Network address classes are dead
