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
