(CIDR) At the maximum, how many hosts can be identified by the CIDR address 205.12.192.0/20?

Solution

Class C addresses have 24 bits of network number and 8 bits of host

number. CIDR address 205.12.192.0/20 spans 4096 addresses

addr: 1100 1101 0000 1100 11000000 0000 0000split:<-------------Net-------------><-----Host------>

2^12 = 4096 new addresses

Range: 205.12.192.0 - 205.12.207.255
